Hello There,
Thanks for the very detailed post information. How did you updated the theme by the way? Did you manually uploaded the files or you have used the automatic updates in your WP dashboard? I have checked everything and it seems that all the settings were correct. No JS error on the page as well. You might need to manually upload the theme files again as there might be some files corrupted during your update process. Simply download a fresh copy of the x.zip file from your dashboard (https://theme.co/apex/dashboard). Unzip this file, logged in to your ftp and upload the files in wp-content/themes/x/ folder.
Hope this helps. Please let us know how it goes.
