What Triggers the WordPress 500 Internal Server Error?

The WordPress 500 Internal Server Error often stems from a corrupted .htaccess file or conflicts between WordPress themes and plugins. These issues mess up how the server handles requests, leading to a breakdown in site functionality.

When tackling this HTTP 500 error, a smart move is to backtrack. Think about the last thing you did before your site crashed-maybe a plugin update or a theme change. Pinpointing that moment can help you zero in on the right fix from the many possible solutions.

Solution 1: Refresh and Clear Browser Cache

First things first, hit that refresh button on your browser. Sometimes, a WordPress 500 Server Error is just a temporary glitch. Servers can get overloaded or hiccup, and a quick reload might snap everything back to normal. It’s the easiest trick in the book to fix this error.

If refreshing doesn’t do the job, your browser might be clinging to old, outdated data causing this WordPress error. Clearing the browser cache gives it a fresh start. Head to your browser settings, wipe out the cookies and cached files, and reload your site.

Delete browser cache and cookies

This forces the browser to grab the latest version of your page, which can often resolve the internal server error. Still seeing that pesky 500 error? No sweat-move on to the next fix.

Solution 2: Purge WordPress Cache

If your WordPress site uses a caching plugin, it might be serving up an outdated or corrupted version of your pages. That can fake a WordPress 500 Server Error, making it seem like the issue persists even after you’ve tried other fixes. Caching plugins like LiteSpeed Cache, WP Super Cache, WP Rocket, or W3 Total Cache store static versions of your site to speed things up, but sometimes that stored data clashes with server-side changes. Log into your WordPress dashboard, navigate to the settings of your caching plugin, and look for options like “Clear Cache,” “Delete Cache,” or “Purge All Caches.” Hit that button to wipe out the old data, then reload your site to see if the HTTP 500 error vanishes.

Clearing the WordPress cache forces your site to load a fresh version of your pages, which can resolve internal server errors caused by outdated or conflicting cached files. For example, in LiteSpeed Cache, hover over the toolbar menu in your dashboard and click “Purge All” from the dropdown.

After clearing, check your site again to confirm the WordPress error is gone.

Solution 3: Deactivate Plugins One by One

Plugins can be sneaky troublemakers behind a WordPress 500 Server Error. They clash, break, or just don’t play nice after an update. Many times, a bug in one of your installed plugins is the root cause of this server error. Go to your WordPress dashboard, head to the Plugins section, and turn them off one at a time. Check your site after each deactivation. If the error disappears, update, replace or remove that plugin to resolve the WordPress internal server issue. Can’t access the dashboard due to the error? No problem. Use an FTP client or your hosting’s file manager to navigate to the /wp-content/ folder and rename the “plugins” folder to something like “plugins.old” This forces WordPress to disable all plugins since it can’t find the folder. Reload your site to see if the error clears up.

If renaming the folder fixes the WordPress error, rename it back to “plugins” to restore access, but note that all plugins will still be deactivated. Now, head to your dashboard and start activating each plugin one by one, refreshing your site after each activation. If the 500 internal server error pops up again after turning on a specific plugin, you’ve found the culprit. Reach out to the plugin’s developers to report the bug and request a fix or update.

Solution 4: Switch to a Default Theme

Your theme might be the root of this WordPress internal server error. A buggy or outdated theme can conflict with plugins or WordPress itself. Head to Appearance > Themes in your dashboard and activate a default one like Twenty Twenty-Five. If the 500 error clears, your old theme’s the issue-time to update or swap it.

No dashboard access? Use FTP to rename the “themes” folder temporarily and let WordPress fall back to a default.

Solution 5: Boost the PHP Memory Limit

Running out of PHP memory can trigger a WordPress 500 Server Error, especially with heavy traffic or resource-hungry plugins. When your site exceeds the allocated memory limit, it can crash, leaving you with that dreaded HTTP 500 error. You can increase the PHP memory limit by editing key files like wp-config.php or .htaccess.

WordPress site health php memory limit

Start with the wp-config.php file, located in your WordPress root directory. Use an FTP client or your hosting’s file manager to access it, then add a line like define(‘WP_MEMORY_LIMIT’, ‘512M’); just above the line that says, “That’s all, stop editing! Happy blogging.” Save the file, upload it back to your server, and check if the WordPress internal server issue is resolved.

Not comfy with code? No problem-ask your hosting provider to handle this server error fix for you. Many hosts, especially those using cPanel, allow you to adjust the PHP memory limit directly from their control panel under “PHP Options” or “PHP Configuration.” After making changes, reload your site to see if it’s back online.

Solution 6: Check the .htaccess File

Next common culprit for the WordPress 500 Server Error: a messed-up .htaccess file. This little file controls how your server behaves, managing stuff like redirects and permalinks, and one wrong line can tank your entire site. A corrupted or misconfigured .htaccess file can confuse the server, stopping it from loading your WordPress site properly and triggering the HTTP 500 error. Use an FTP client like FileZilla or your hosting’s file manager to find it in the root directory of your WordPress installation, often in the same folder as wp-content and wp-admin. Rename it to something like “.htaccess_old” to disable it temporarily. Then, reload your site to see if it works. If it does, you’ve nailed the issue-the old .htaccess file was the problem.

WordPress htaccess file

If renaming fixes the WordPress error, it’s time to create a fresh .htaccess file. Log into your WordPress dashboard, head to Settings > Permalinks, and hit “Save Changes” without tweaking anything. This tells WordPress to generate a new default .htaccess file with the correct rewrite rules to handle URLs. If WordPress can’t write the file due to permission issues, create it manually via FTP by adding the default code (available on WordPress.org) to a new .htaccess file. Make sure the file permissions are set to 644 so the server can read it. After regenerating, clear your browser cache and check if the WordPress 500 Server Error is gone.

Solution 7: Peek at Error Logs

Error logs are your detective tool for cracking any site errors. Most hosting providers keep detailed error logs that track server-side problems, and you can usually find these by logging into your hosting control panel (like cPanel or Plesk) and looking for sections labeled “Logs” or “Error Logs”. In cPanel, for example, you’d go to Metrics > Errors to see the latest entries. These logs list recent errors and often point directly to the file or process causing the HTTP 500 error.

If you can’t find what you need in your hosting dashboard, WordPress has its own way to help you dig deeper. You can enable debugging by adding a few lines to your wp-config.php file:

define('WP_DEBUG', true);
define('WP_DEBUG_LOG', true);
define('WP_DEBUG_DISPLAY', false);

This will create a debug.log file in your wp-content folder, where you can check for detailed error messages. If the log entries look like gibberish, copy the error message and search for it online, or reach out to your host’s support team for help. Reading these logs often points you straight to the WordPress glitch, so you can fix the issue fast and get your site back online.

Solution 8: Re-Upload Core WordPress Files

If you’ve tried everything else and the 500 Server Error still won’t budge, your core WordPress files might be corrupted. This can happen after a failed update, malware infection, or just random file corruption. The fix? Download the latest version of WordPress from the official website. Unzip the file on your computer, but make sure you don’t touch your wp-content folder or wp-config.php file – those hold your themes, plugins, and site settings. Using an FTP client, connect to your site’s root directory and upload the fresh WordPress files, overwriting the existing ones. When prompted, select “Overwrite” and apply it to all files in the queue. This process replaces only the core files, so your content and settings stay safe.

After the upload, refresh your site and see if the 500 error is gone. Re-uploading core files often wipes out any corrupted files causing the issue, giving your site a clean slate without affecting your posts, themes, or plugins. Always use a back up plugin for your website before making these changes, just in case something goes sideways. If you’re not comfortable with FTP or file management, ask your hosting provider for help.

Solution 9: Contact Your Hosting Provider

If you’ve tried every fix and that WordPress 500 Server Error still won’t budge, it’s time to bring in your hosting provider. These folks have access to the server-side tools and logs you can’t reach, so they can quickly spot issues like database connection problems, PHP misconfigurations, or resource limits being hit. Sometimes the error is tied to things only your host can see or fix-think server permissions, ownership conflicts, or advanced debugging that goes beyond the WordPress dashboard. Just open a support ticket, or call their help desk and let them know what you’ve already tried.

Most hosting providers are used to dealing with internal server errors and can jump in to squash the issue fast. They’ll check the server logs for you, adjust settings if needed, and get your site back online. If you’re on managed WordPress hosting, this is often the quickest and easiest way to resolve HTTP 500 errors. Don’t hesitate to reach out-sometimes, letting the pros handle it is the smartest move, especially if downtime is costing you visitors or sales. If your host resolves the problem, ask them what caused it so you can prevent it in the future.
