Most people who use WordPress will eventually experience a 500 Internal Server Error.
What Causes the 500 Internal Server Error?
The 500 Internal Server Error is usually caused by a mistake or error in your WordPress code which prevents the 500 error from being displayed. When this occurs, WordPress sends a 500 Internal Server Error and displays an “Error 500” page to let you know that there was a problem on the server.
If you’re using WordPress, there are two main causes for the 500 Internal Server Error:
- A plugin or theme that is not compatible with WordPress
- A problem with your server’s configuration
Practically Fix the 500 Internal Server Error in WordPress
There are several things you can do to alleviate the 500 Internal Server Error in WordPress. Here are some of the most popular remedies:
1. WordPress Backup Creation:
You are not always responsible for any problems that arise on your hosted server. Humans may make mistakes, just as servers can since they are controlled by people. Some of these issues are major, and if not addressed, they may harm the integrity of your entire website. Backing up site data on your server should therefore be a required habit.
However, if your hosting company does not provide you with the proper tools for backing up WordPress website data, you may utilize the WordPress Backup Plugins.
2. How to Fix a 500 Internal Server Error on Your WordPress Website
Any mistake may be easily fixed with a little research. Analysis of the problem’s root cause can assist you in determining what is causing it; this may help you get a handle on the situation. There are a variety of reasons why the WordPress website may generate a 500 internal server error.
To address this recurring problem, you must first determine the source of the problem. The most common reasons for this error are corrupt .htaccess files and a restrictive PHP memory limit. So without further ado, let’s get started on how to fix them.
3. The .htaccess File Error Fix
The file most often used by PHP-based applications is the .htaccess file. This file contains server-related configuration directives. This can result in a 500 internal server error if your .htaccess file is damaged. A theme’s or module’s malfunction, a broken installation of a plugin, or similar factors can all cause the .htaccess file to become corrupt. To fix the problem, start by looking at your .htaccess file. To discover this problem, log in to your FTP account. The file will be accessible to you in the root directory, alongside other folders such as wp-content, wp-includes, and admin.
You can now download your .htaccess file from the live server to a local PC location. Then open this file in your text editor (Notepad++, Dreamweaver, etc.).
The syntax of the code varies depending on your WordPress setup and installation. If you’re using WordPress Multisite in a WordPress 3.5 or later version, use the following text:
=============================================================
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ – [L]
# add a trailing slash to /wp-admin
RewriteRule ^([_0-9a-zA-Z-]+/)?wp-admin$ $1wp-admin/ [R=301,L]
RewriteCond %{REQUEST_FILENAME} -f [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^ – [L]
RewriteRule ^([_0-9a-zA-Z-]+/)?(wp-(content|admin|includes).*) $2 [L]
RewriteRule ^([_0-9a-zA-Z-]+/)?(.*\.php)$ $2 [L]
RewriteRule . index.php [L]
==============================================================
Reload your website to see whether the 500 internal server error has been resolved. If you’re lucky, everything should be fine; if not, keep reading.
4. Improve WordPress Performance by Increasing the PHP Memory Limit
When a user makes an HTTP request, it is handled by PHP and eventually results in the client receiving HTML. The operating system allocates memory to execute this program. Increasing the PHP Memory Limit is another approach to resolving the 500 internal server error.
The default PHP memory limits are set by your host and WordPress. When you see a memory vacuum, your server instantly displays a 500 internal server error. To prevent this, simply increase the PHP memory limit in WordPress and ensure that your website is running properly again. By doing so, you may avoid the 500 internal server errors from occurring on your website very frequently.
By editing one of these files, you may increase a WordPress website’s PHP memory limits in several ways. However, these are some of the most frequent methods:
.htaccess File
You may also increase the PHP memory limit using a .htaccess file. Simply go to your root directory and look for a .htaccess file. Select the Save option from your browser’s menu to save this file on your PC. Now, open the URL in a text editor and add this code after the PHP tag:
php_value upload_max_filesize 64M
php_value post_max_size 64M
WP-Config File
You may also increase the PHP memory limit by modifying wp-config.php in your WordPress installation’s root directory. Locate wp-config.php in your WordPress installation’s root directory and modify it as needed. To save it to your computer, right-click on the file and select Download. Open the file in a text editor and add the following code after the PHP tag:
define(‘WP_MEMORY_LIMIT’, ’64M’);
ini_set(‘post_max_size’, ’64M’);
ini_set(‘upload_max_filesize’, ’64M’);
PHP.ini File
You must save the following code in your php.ini file. In the wp-admin/ directory, upload the following code.
- memory_limit = 64M
- upload_max_filesize = 64M
- post_max_size = 64M
- file_uploads = On
If these two possible solutions don’t work, there are a few more options for avoiding the 500 Error in your WordPress website.
Plugins Audit
Plugins that are out of date or faulty might cause problems with WordPress, resulting in malfunctions. Similarly, they’re a risk to your site’s security if they’re not kept up to date with the most recent WordPress security updates.
If you have administrator access to your WordPress site, deactivate each plugin one at a time. After each deactivation, refresh your website.
Try going to your website again. If the issue persists, check to see whether there is a plugin installed on your WordPress. Now, you must activate each plugin one at a time and refresh your website after each activation. The corrupt plugin will be recognized as soon as it causes a 500 Error for your website.
Wp-Admin & Wp-Includes [New]
Sometimes it’s more difficult than one might think to solve a problem. The WordPress website is made up of third-party themes and plugins, which means auditing their source code isn’t easy. In this section, you must download and upload the new wp-admin and wp-content folders to the live host via FTP. Before you begin, make sure you’ve backed up the website.
Contact Your Hosting Provider
If the issue persists after being investigated for these most common causes, you should contact your hosting provider. In addition, you may submit a request to the technical specialists to help you solve your problem by going through your server settings.
There are multiple Error messages since they are all server-side problems. The 502 Bad Gateway Error is one example of a 500 problem.
