WordPress is a popular content management system (CMS) that powers millions of websites worldwide. It is a flexible and user-friendly platform that allows you to create and manage your website with ease. However, like any other software, WordPress is not immune to errors. One of the most common errors that WordPress users encounter is the “500 Internal Server Error.” This error can be frustrating and can leave you wondering what to do next. In this article, we will explore what the 500 Internal Server Error is, what causes it, and how to fix it.
What is the 500 Internal Server Error?
The 500 Internal Server Error is an HTTP status code that indicates something has gone wrong on the server, but the server cannot identify the specific problem. It is a generic error message that can be caused by various factors.
When you encounter the 500 Internal Server Error on your WordPress site, you may see a message like this: “Internal Server Error – The server encountered an internal error or misconfiguration and was unable to complete your request.”
What Causes the 500 Internal Server Error?
There are several reasons why the 500 Internal Server Error may occur on your WordPress site. Some of the most common causes include:
Corrupted .htaccess File
The .htaccess file is an important file that controls how your website functions. If this file is corrupted or contains incorrect code, it can cause the 500 Internal Server Error. This is often caused by an incomplete or incorrect code snippet added to the file, or by a plugin or theme that modifies the file.
Plugin or Theme Conflict
Plugins and themes are essential components of any WordPress site. However, they can sometimes conflict with each other, causing the 500 Internal Server Error. This can occur when a plugin or theme is outdated, incompatible with your version of WordPress, or conflicts with another plugin or theme.
Insufficient Memory Limit
WordPress requires a certain amount of memory to function correctly. If your site exceeds the memory limit, it can cause the 500 Internal Server Error. This is often caused by a large number of plugins, poorly optimized code, or insufficient server resources.
PHP Version Compatibility Issues
WordPress relies on PHP to function correctly. If your version of PHP is outdated or incompatible with your version of WordPress, it can cause the 500 Internal Server Error. This is often caused by using an outdated version of PHP or by not updating your PHP version when prompted.
Server Configuration Issues
Sometimes, the 500 Internal Server Error can be caused by server configuration issues. This can occur if the server is overloaded, misconfigured, or experiencing downtime.
How to Fix the 500 Internal Server Error?
Now that we have identified some of the common causes of the 500 Internal Server Error, let’s look at how to fix it.
Step 1: Check the .htaccess File
To check the .htaccess file, you will need to access your website’s files using an FTP client or the file manager in your web hosting control panel. Look for the .htaccess file in the root directory of your website, and rename it to something like “htaccess_backup.” This will disable the file temporarily. Then, try accessing your website again. If the 500 Internal Server Error is resolved, it means the .htaccess file was the culprit.
You can create a new .htaccess file by logging in to your WordPress dashboard, navigating to Settings > Permalinks, and clicking the “Save Changes” button without making any changes. This will generate a new .htaccess file with default settings.
The empty file will open in a plain text editor like Notepad or TextEdit. Now, you need to copy and paste the following code inside it.
# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>
# END WordPress
Step 2: Deactivate Plugins and Themes
If the 500 Internal Server Error is not resolved by checking the .htaccess file, the next step is to deactivate your plugins and themes. This will help you identify if a plugin or theme is causing the issue.
To deactivate your plugins, log in to your WordPress dashboard, navigate to the Plugins page, and select all plugins. From the Bulk Actions drop-down menu, select “Deactivate,” and click the Apply button. Then, try accessing your website again. If the 500 Internal Server Error is resolved, reactivate your plugins one by one until you identify the plugin causing the issue.
To deactivate your theme, access your website’s files using an FTP client or the file manager in your web hosting control panel. Look for the “wp-content/themes” directory, and rename your active theme’s folder. This will force WordPress to use the default theme. Then, try accessing your website again. If the 500 Internal Server Error is resolved, it means your theme was causing the issue.
Step 3: Increase Memory Limit
If the 500 Internal Server Error is not resolved by checking the .htaccess file and deactivating plugins and themes, the next step is to increase your memory limit. To do this, you will need to edit your website’s wp-config.php file.
Access your website’s files using an FTP client or the file manager in your web hosting control panel. Look for the wp-config.php file, and open it in a text editor. Add the following line of code before the line that says “/* That’s all, stop editing! Happy blogging. */”:
define('WP_MEMORY_LIMIT', '256M');
This will increase your memory limit to 256MB. Save the changes and upload the file to your server. Then, try accessing your website again.
Step 4: Update PHP Version
If the 500 Internal Server Error is still not resolved, the next step is to update your PHP version. You can do this by logging in to your web hosting control panel and navigating to the PHP version section. Select the latest version of PHP available and save the changes. Then, try accessing your website again.
Step 5: Contact Your Web Host
If none of the above steps resolve the 500 Internal Server Error, the issue may be with your web host. Contact your web host’s support team and provide them with details about the error you are experiencing. They will be able to investigate the issue and provide you with a solution.
