I’m not sure if this goes here but, I had an issue after updating wordpress, the add media button wouldn’t do anything. No error message it just sat there when clicking on it. Adding (without quotes) “define(‘SCRIPT_DEBUG’, true);” to the wp-config.php file fixed this issue for me.
Sorry should have worded that better, first time posting a workaround/fix for anything. I tried that master list and didn’t see anything related to my issue. I’ll keep looking around for a better solution.
