Revolution slider critical error

Every time I activate Rev slider is creates a critical error on the public side. I have deactivated the majority of plugins and it keeps happening. Please advise.

Hello @kstidham,

It might be the issue of version compatibility. Please make sure your theme, plugins, WordPress, and the PHP version are updated as per our version compatibility page.. I noticed you are using an older version of the plugin. I would suggest you please purge all the cache. I would suggest you troubleshoot with a few of the common issues before we investigate your settings.

  1. Testing For Theme Related Issue
  2. Testing For Plugin Conflict
  3. Theme Update
  4. Child Theme
  5. Css/Js Customization
  6. Increasing Php Memory Limit
  7. Disabling Cache
  8. Disabling Cdn
  9. Permalinks
  10. Version Compatibility

If it doesn’t work, please copy your live site to a staging server so we could troubleshoot freely without breaking your live site. Please share your staging server login details with FTP. Please add the below-given code into your wp-config.php for debugging setup and the error logged into the file name debug.log inside the wp-content folder.

You can let us know if you find any error that is related to our theme or theme bundled plugins. We can do further investigation based on that.

// 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 );
//SET PHP INI DISPLAY ERROR FALSE
@ini_set( 'display_errors', 0 );

Please find the video that will help you to edit wp-config.php and add the above code: https://www.youtube.com/watch?v=3SDPTafEM8o
