    Today i’ve upgraded my PHP version to 7.3 and everything was working fine with WordPress 5.1 only some slower.
    The next step was to update plugins, i wanted to upgrade the following plugins;

      UpdraftPlus
      Divi Builder
      Bloom
      Monarch

    After a few minutes an error 500 occured. Then i’ve cleared my browser cache and reloaded the wp-admin page (which is different with the wps hide login plugin). It only shows an blank page with no error at all.

    After some researh i’ve rolled back to PHP version 7.2 and removed the failed update plugins from the wp-content folder and readded them via FTP from an restore point yesterday. No progress at all.

    The next step was to add the following rules to wp-config file so an debug.log would be created;
    define( ‘WP_DEBUG’, true );
    define( ‘WP_DEBUG_DISPLAY’, false );
    define( ‘WP_DEBUG_LOG’, true );

    I’ve reloaded the page with different browsers and cleared the cache. But no debug.log file is created.

    What’s the next step to troubleshoot this issue?

    Via FTP or your hosting control panel, access wp-content/plugins and rename the directories of the plugins you just updated (e.g., to myplugin.xxx) and do the same in wp-content/themes for the updated themes.

    If that gets you your site back, rename them back one at a time until you figure out what broke the site.

    Alternatively, download fresh copies of each from their original sources and unzip locally. Then delete each of their directories and upload the directories into which they were unzipped.

    That was the trick thanks! But the other question why there’s no debug log isn’t clear for me yet.
