Seeing a white screen or getting a vague “critical error” message on your website? Yeah, that’s one of the worst moments for any site owner. This problem—the 500 internal server error wordpress—usually shows up out of nowhere, locking you out of your dashboard and blocking visitors from seeing your content. The really annoying part? The error message tells you basically nothing about what actually went wrong, which leaves most people staring at their screen wondering where to even start.
This guide cuts through the confusion around fixing the http error 500 wordpress. Maybe your site crashed right after an update, or you’re dealing with a 500 internal server error that just appeared for no obvious reason—either way, we’ll go through the solutions that actually work to get things running again. We’ll use a step-by-step approach to figure out if the culprit is one of your plugins, your theme, or something happening at the server level.
In the sections ahead, we’ll dig into what causes an internal server error wordpress and give you practical steps to fix it. We’re covering everything from quick fixes like resetting your configuration files to more technical server adjustments. The goal here is simple: get your site back up fast and help you understand how to avoid these headaches down the road.
What Is the 500 Internal Server Error in WordPress?
A 500 internal server error wordpress is basically the server’s way of saying “something broke, but I’m not sure what.” It’s one of those frustratingly vague error messages that doesn’t tell you much about what actually went wrong. In the world of HTTP response codes, anything in the 500 range means the problem is on the server’s end. Unlike a 404 error that tells you a page doesn’t exist, or a 403 that means you’re not allowed in, the 500 error is the server throwing up its hands and admitting it hit a snag it can’t identify.
Here’s what happens behind the scenes: when you visit a website, your browser asks the server for the page. The server processes that request and sends back what you need, along with some technical info in the HTTP header. But if something goes wrong during that process—maybe a script took too long to run, the server ran out of memory, or there’s a problem in the code—you get the wordpress 500 error. Since this happens on the server side, your browser doesn’t get any useful information to show you. That’s why you usually just see a blank page or a generic error message from Apache or Nginx.
WordPress sites seem to run into this error more often because there’s a lot going on under the hood. You’ve got PHP scripts running, a database getting queried, and all those plugins and themes doing their thing. Every time someone loads a page, the server has to execute a bunch of code. If just one plugin has a typo in its code, or your theme tries to use more memory than your hosting plan allows, the whole thing can fall apart. Most of the time, the 500 internal server error wordpress shows up because of something in your configuration files or because a plugin you just updated doesn’t play nice with your version of PHP. Once you understand it’s a server problem, you can start figuring out which piece of your site is causing the trouble.
Symptoms and Impact
Spotting wordpress 500 error symptoms usually starts when your website suddenly stops loading the way it should. You might pull up your site expecting to see your homepage, only to find a completely blank white screen—something people in the WordPress world call the White Screen of Death. Other times, your browser throws up a generic message like “Internal Server Error” or “The server encountered an internal error or misconfiguration and was unable to complete your request.” These messages are deliberately vague because the server doesn’t want to expose sensitive details about what went wrong in your code.
How badly this error affects you really depends on what’s causing it. Sometimes the wordpress 500 error impact only hits your front-end, which means visitors can’t see your site, but you can still get into your dashboard at /wp-admin. When things get worse, the error takes over everything—you’re completely locked out of the admin area. That means you can’t deactivate plugins or switch themes the normal way, and suddenly the whole situation feels pretty urgent.
But the wordpress 500 error impact goes way beyond just being locked out. Search engines don’t like seeing 500 errors. If Google’s crawler stops by while your site is broken, it might pull your pages from search results so it doesn’t send people to a dead link. And when visitors hit a broken site, they start wondering if you’ve abandoned it or if there’s a security problem. That kind of impression can cost you traffic and sales pretty quickly. Getting on top of these symptoms fast is really the only way to prevent lasting damage to your online presence.
Step-by-Step Fixes for the WordPress Internal Server Error
When your website breaks, you need a clear plan of attack. The wordpress 500 error fix can be anything from tweaking a simple setting to diving into server configurations, so tackling the obvious problems first will save you hours of frustration. What you’re really trying to do is figure out which piece—a file, plugin, or server setting—is causing everything to fall apart.
I’ve organized these fixes in an order that makes sense. We’ll start with easy, low-risk solutions like checking for corrupted files before getting into the heavier stuff like permissions and server logs. If you just installed something new or updated WordPress, start there. But if this error came out of nowhere? You’re probably looking at a server resource issue or a background update that didn’t go as planned.
Check and Regenerate the .htaccess File
A corrupted configuration file is one of the biggest reasons you’ll run into a wordpress .htaccess problem that triggers a 500 error. This file handles redirects and permalinks on Apache servers. Here’s what to do: grab an FTP client or use File Manager, find .htaccess in your root directory, and rename it to .htaccess_old. Site loads now? That was your problem. To get a fresh version, just head to Settings > Permalinks in your dashboard and hit Save Changes.
Increase the PHP Memory Limit in WordPress
Your site might be crashing because it’s run out of memory. To increase wordpress memory limit, pop open wp-config.php and drop in this line: define(‘WP_MEMORY_LIMIT’, ‘256M’); right before the “Happy publishing” comment. You can also learn how to increase wordpress memory through your hosting panel by finding the memory_limit setting under PHP configuration. If the error vanishes, you just needed more headroom.
Disable All Plugins and Identify the Problematic One
A wordpress plugin error is behind a lot of these crashes, usually after an update creates a conflict. Can’t get into your dashboard? Use FTP to rename the plugins folder (it’s in wp-content) to something like plugins_old. Site back? Good. Now rename it back to plugins and turn them on one at a time. This way you’ll catch exactly which one is causing trouble.
Switch to a Default WordPress Theme
If plugins check out fine, you might have a wordpress theme error on your hands, especially if things broke after updating your theme or editing code. Via FTP, go to wp-content/themes and rename your active theme’s folder. WordPress will kick over to a default theme automatically. If that clears the 500 error, the problem’s hiding in your theme’s functions.php or template files.
Re-upload Core WordPress Files
Sometimes the core wordpress files get corrupted or don’t update properly. Download a fresh WordPress copy and upload just the wp-admin and wp-includes folders via FTP, replacing what’s there. Leave wp-content alone—that’s where all your images, themes, and plugins live. This gives you a clean engine without touching your actual content.
Check File and Folder Permissions
Wrong wordpress folder permissions can make your server refuse to cooperate, throwing a 500 error. The standard setup is 755 for folders and 644 for files. Check these in your FTP client. If something’s set too open or the server can’t write where it needs to, it’ll shut down script execution as a safety measure, which gives you that generic error.
Enable Debug Mode and Review Server Logs
Instead of staring at a vague error message, turn on wordpress debug. In wp-config.php, flip define(‘WP_DEBUG’, false); to true. Now you’ll see actual PHP errors. Also check your wordpress error logs through your host or look for an error_log file in your root directory. These logs show you exactly what failed and when, which beats guessing any day.
Web Hosting and PHP Configuration Issues
Sometimes the problem isn’t your site—it’s the environment. A server error 500 wordpress can stem from a wordpress php error if you’re running an old or incompatible PHP version. On a wordpress vps, make sure all required PHP modules are active and execution timeouts aren’t set ridiculously low. For high-traffic sites dealing with repeated issues, a performance-tuned wordpress vps gives you the stability and custom settings to avoid these configuration headaches.
Fixing a 500 Internal Server Error in wp-admin
You might hit a situation where the 500 internal server error wordpress wp-admin only happens when you try to access your dashboard while the front end works fine. This wordpress 500 error usually means you’re short on memory for admin tasks or there’s a conflict with a backend-only plugin. To fix this 500 internal server error wordpress, clear your browser cache and cookies first, then bump up the memory limit or deactivate admin plugins one by one.
How to Prevent WordPress 500 Internal Server Errors
Nobody wants to deal with an internal server error wordpress situation, but you can avoid a lot of headaches by staying ahead of problems before they happen. Rather than scrambling when your site crashes, a few simple habits can keep things running smoothly.
The biggest thing? Backups. Seriously, back up your site before you touch anything. Updating a plugin, swapping themes, tweaking code—whatever it is, make sure you’ve got a full backup first. That way, if a wordpress 500 internal server error pops up, you can roll everything back and get your site working again without losing hours of work.
Next up: don’t turn your site into a plugin graveyard. Every plugin you install is another piece of code that could clash with something else and trigger a 500 internal server error wordpress. Go through your plugins and themes every few months and delete the ones you’re not actually using. Also, keep your PHP version current. Running outdated PHP is one of the most common reasons people hit a wordpress 500. As WordPress and its plugins evolve, they stop supporting older PHP versions, so staying updated means fewer compatibility issues and a more secure site overall—plus you’re way less likely to run into a wordpress internal server error.
And honestly, your hosting matters more than you think. A lot of these errors happen because your server just can’t handle the load. If you’re still on basic shared hosting but your site’s grown, you might start seeing timeouts and memory crashes. Upgrading to a better hosting plan where you actually have control over server settings can eliminate most of the usual triggers for a wordpress 500 internal server error. Oh, and use the Site Health tool in your WordPress dashboard—it’ll flag potential issues before they blow up into full-on site failures.
WordPress 500 Internal Server Error FAQ

Conclusion
Fixing a wordpress 500 error takes some patience, but usually it comes down to three things: a plugin acting up, something wrong with your configuration files, or your server running out of steam. The troubleshooting steps we’ve covered—checking your .htaccess file first, then disabling plugins one by one, and bumping up your memory limits—should get your site running again even if you’re not a developer.
After you’ve got everything working again, think about how to keep it that way. Regular backups are your safety net. Keep PHP updated. And seriously consider whether your hosting plan actually gives you enough resources to work with.
