HTTP error 500 on Hosting

I get an HTTP error 500. This happened after I uploaded and activated a few new plugins that were required for my theme.

    Hello Jeff

    We need the debug information. Would you please enable debug mode and check if there is any error? To enable debug mode please go to wp-config.php and change

    define( 'WP_DEBUG', false );

    to

    define( 'WP_DEBUG', true );
    
define( 'WP_DEBUG_DISPLAY', false );
    
define( 'WP_DEBUG_LOG', true );

    Now refresh the page. That will create a file called debug.log inside wp-content folder. Open that file, check the very bottom and you will see the latest errors. Please send me those.

    Have a nice day!

    Cheers,

    Ash

    I fixed it, thanks for the help.

    I went into the wp-contents folder and

    mv plugins plugins.no

    to deactivate the responsible plugin.

    Then I signed into the WordPress Admin and

    mv plugins.no plugins

    to show all the installed (but deactivated) plugins and went through them one by one. I believe the OI-shortcodes was the one that was the culprit, I re-up’ed it and it seems to be fine now.

    Thanks for the help!
