500 Internal Server Error on WordPress when trying to install

  • Katya Tsihotska

    Hi Purmanund

    Hope you're having a wonderful day!

    I've tried to replicate this issue on my test install, but it didn't cause any errors for me. In order to diagnose your issue, I'd request you to perform the two tests mentioned in the following:

    1. Just to make sure no other plugin is causing this, can you please do a plugin conflict test?
    The simplest way to perform a plugin conflict test:
    * Login to your site via FTP
    * Navigate to wp-content
    * Rename the plugins folder to _plugins
    * Create a new empty plugins folder
    * Move the plugin folder (ex: jobs-plus) you want to test from _plugins to plugins
    * Check if the issue still persists, if no, proceed to the next step
    * Then, one at a time, move other plugin folders over from _plugins to plugins until the symptom returns

    NOTE: While you are doing this, do not visit WP Admin > Plugins on your site. This will ensure that your plugins remain active when you copy them back over.

    Let us know about results.

    2. Also, as "500 Internal Server Error" by itself doesn't give much information, I would request you to enable wp debug. To enable WP_DEBUG, change the following line in your wp-config.php file:
    define('WP_DEBUG', false);
    To this:

    // Enable WP_DEBUG mode
    define( 'WP_DEBUG', true );
    // Enable Debug logging to the /wp-content/debug.log file
    define( 'WP_DEBUG_LOG', true );
    // Disable display of errors and warnings
    define( 'WP_DEBUG_DISPLAY', false );
    @ini_set( 'display_errors', 0 );

    Please make sure to add the above code just before the line /* That's all, stop editing! Happy blogging. */

    After this, try to replicate issue again. Then go to /wp-content folder and check if debug.log file is there. If it's there. download it, save as debug.txt and attach to your next reply.

    Also, could you please grant us temporary support access to your website so we can have a better look at your setup and settings? You can grant us access via WPMUDEV Dashboard plugin, there's no need to share credentials. Here's our detailed documentation page about it:

    Kind regards,
