WordPress has grown to become one of the most popular content management systems available today, powering millions of websites. Trusted by bloggers and corporations because of its extreme versatility, huge support base – and it doesn\u2019t cost a thing. Still, it sometimes throws up errors that can be a challenge to fix, even after using the documentation available. One such error is \u201cWordPress 500 Internal Server Error<\/strong>.\u201d<\/p>\n

It\u2019s quite common and can keep your site offline if you don\u2019t fix it. Just follow the steps below and you should be back up and running in no time. And please note that any time you\u2019re thinking of making changes, back up your WordPress site and its MySQL database. It\u2019s always best to ensure you can recover your site if something goes wrong.<\/p>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

Enable debugging to fix WordPress internal server error<\/h2>

Debugging is always going to be a part of working with PHP. And WordPress comes with its own systems which simplify the process. You can enable debugging in WordPress by connecting to your server via FTP\/SFTP or SSH. Once you\u2019re in, edit the wp-config.php file. Just before the \/* That\u2019s all, stop editing! Happy blogging. *\/<\/strong> line, add these lines:<\/p>

define('WP_DEBUG', true);<\/code><\/p>

define('WP_DEBUG_LOG', true);<\/code><\/p>

WP_DEBUG<\/strong> is a PHP constant which triggers the debug mode in WordPress. WP_DEBUG_LOG<\/strong> ensures that all errors are saved in a log file called debug.log.<\/p>

Save the configuration file and then whichever WordPress operation caused the WordPress 500 Internal Server Error, do it again. Look in the \/wp-content\/ directory. Locate the debug.log log file and check it for PHP errors, warnings, and notices. If you find any you can attempt to fix them.<\/p>

You should ideally have the following code in your wp-config.php file:<\/p>

Enable WP_DEBUG mode:<\/p>

define( 'WP_DEBUG', true );<\/code><\/p>

Enable Debug logging to the \/wp-content\/debug.log file:<\/p>

define( 'WP_DEBUG_LOG', true );<\/code><\/p>

Disable display of errors and warnings:<\/p>

define( 'WP_DEBUG_DISPLAY', false );<\/code><\/p>

@ini_set( 'display_errors', 0 );<\/code><\/p>

Use dev versions of core JS and CSS files (only needed if you are modifying these core files):<\/p>

define( 'SCRIPT_DEBUG', true );<\/code><\/p>

\"Server<\/a><\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Increase PHP memory limit in WordPress to fix internal server error<\/h2>\n

One of the most common causes for the 500 Internal Server Error<\/strong> message is hitting the PHP memory limit. This is normally set in the php.ini file, so you can try increasing the \u00a0memory_limit<\/strong> in php.ini and restart your Apache HTTP server \/ PHP-FPM service. Alternatively you can add the following line in your wp-config.php file:<\/p>\n

define('WP_MEMORY_LIMIT', '64M');<\/code><\/p>\n

In case your application is struggling under multiple active plug-ins and a heavy theme, you can add memory by increasing the value here.<\/p>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

\n\t\t\t\t
\n\t\t\t\t\t\t\t

Create new .htaccess file<\/h2>\n

The .htaccess file can easily become corrupted by a bad plugin or manual changes. Log in to your server via FTP\/SFTP or SSH and rename the file to .htaccess.BAK or .htaccess.CORRUPTED. Then create a new .htaccess file with the basic .htaccess settings.<\/p>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

\n\t\t\t\t
\n\t\t\t\t\t\t\t

Deactivate all plugins in WordPress to fix internal server error<\/h2>\n

If none of these approaches works, it may help to deactivate all your WordPress plugins. Go to the WordPress dashboard and find the Plugins<\/strong> section, then deactivate them, one at a time. Each time you do this, you can refresh your site and then check to see if the problem has been solved.<\/p>\n

If you don\u2019t have access the WordPress dashboard you can still deactivate the plugins via FTP\/SFTP or SSH. Log in to your server, go to your wp-content directory and rename the plugins directory to plugins.DEACTIVATED. Alternatively, you can go to the plugins directory and deactivate each plugin one by one. Do not forget to enable the plugins once you are done by renaming the plugins.DEACTIVATED directory to plugins again.<\/p>\n

With any luck, one of these solutions will have helped you to fix the WordPress 500 Internal Server Error. But if not, contact your web hosting provider for assistance.<\/p>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
