When you visit the website, the browser sends a request to the server, where the host is located. The server sends back the requested resources, which include PHP, CSS, and HTML, which also includes the HTTP status code.

How to Fix 500 HTTP errors?

So where to start troubleshooting? You normally have no idea, where to begin.
Let us address the common causes and ways to fix this trouble.

Try to Reload the Page

However, it is obvious, but this is the first thing you should try. May be your host or server is overloaded. If it does not help, paste the link of your site here. It will tell your site is down or the problem is at your side.

Clear The Cache of Your Browser

This is another good option. Do it before you start deep troubleshooting.

However, remember that there is no single technique for all browsers. Instructions are different depending on you have, either Google Chrome, Mozilla Firefox, Safari, Internet Explorer or Microsoft Edge.

A simple google search would show you all these techniques, separately.

Turn on Debugging

This may give you an insight into what is happening. To turn on debugging, you have to edit the wp-config.php file.

Open this file and locate WP_DEBUG within. You must be able to set it to true. It should look like this, in the end.

// Enable WP_DEBUG mode
define( 'WP_DEBUG', true );
// Enable Debug logging to the /wp-content/debug.log file
define( 'WP_DEBUG_LOG', true );
// Use dev versions of core JS and CSS files (only needed if you are modifying these core files)
define( 'SCRIPT_DEBUG', true );

Save it and reload your site. It would be okay now if you were lucky. It is also possible that you encounter a different trouble.

If this happens, locate the trouble. If you find it in any plugin folder, disable that plugin.

Even if turning the debugging on does not give the desired result, keep it on until the problem is resolved.

Plugins and Themes

Deactivate all your plugins if you have access to the dashboard. If the problem solves, this means some of your plugins are misbehaving. Switch them on, one by one to figure out which one it is.

This is also very likely that the issue is caused by some WordPress theme. Always make sure that you install Accessible WordPress themes.

You may also switch your theme to the default and un-altered WordPress themes like Twenty Fifteen or . Does the site now load without host error?

Inspect your .htaccess file

This file contains the number of rules that tell the server what to do in which circumstances. Commonly, it is used for rewriting URLs to or preventing access to your site for malicious intent.

Open your FTP editor to check if you have .htaccess file in your WordPress root folder. Make sure it displays hidden files, too.

If you find the file, there make its backup instantly. Then delete all the content within or deleted the file at all.
Check if the website loads now.

The PHP Memory Limit

Exhausting the PHP memory limit on the server can also be the culprit. Please be sure you have to meet WordPress requirements. Otherwise, Try to increase this limit.

Open the FTP client, and find a wp-config.php file. Right-click and select view/edit. Choose the default editor.
You will find the desired line under the WP_DEBUG line. You can add if it is not there. It should look like this in the end.

    define( 'WP_MAX_MEMORY_LIMIT', '256M' );
    define( 'WP_MEMORY_LIMIT', '256M' );

whole that modifying your wp-config.php file doesn’t fix the problem, you’ll have to address the issue within your server settings . The php.ini file is the default PHP configuration file. Most of the Shared Hosting does not allow access the php.ini file.To increase the PHP memory limit , change these lines in PHP.ini

    memory_limit = 256M
    upload_max_size = 64M
    post_max_size = 64M
    upload_max_filesize = 64M
    max_execution_time = 300
    max_input_time = 1000

In the event, you don’t have access to your php.ini file, then your last resource is to modify .htaccess file. the .htaccess file starts with a dot because it is a hidden file. If you can’t root folder, check to make sure that your SFTP file manager isn’t begin those files hidden from view.

In your .htaccess you can add:

PHP 5.+
php_value memory_limit 64M
PHP 7.+
 php_value memory_limit 64M

Refresh both your FTP client and website. What happens now? PHP memory limit was definitely the issue if everything is ok now.

Try to figure out later, that what is draining the memory. Any poorly hosting, coded plugin or theme can be the issue. The best way to figure out is to contact your hosting provider. Ask them to check the server logs.

Check File Permissions

In your WordPress directory, files should be set to 755 or 644. If they are not, you could end up with a HTTP error on your website. To check this out, log in to your FTP client and look in your site’s directory under Permissions.

You will notice that all folders are set to 755 and everything else on 644. If any of the things are set to something else, change it instantly. Enter the right number.

Coding or Syntax
