 * Hello,
 * Thanks for the feedback. On which admin page are you? Can you please make sure
   you’re using ACF Pro 5.8 or higher? Are you sure you don’t have any other Javascript
   error? Also can you please refresh your browser cache and disable it in your 
   console > network tab?
 * It looks like ACF is not correctly loaded, it’s not normal.
 * Regards.

 * Hi Konrad,
 * It seems updating the ACF plugin to Version 5.9.3 has solved the problem. Or 
   perhaps leaving it some time and the cache my have purged. Not sure exactly but
   it’s working now so all good!
 * Thanks

 * Hello,
 * Yes you’re right. There is a incompatibility issue with the early ACF Pro 5.8.
   x versions and the latest ACF Extended update. See my answer here: [https://wordpress.org/support/topic/acfe-is-not-defined-error/#post-13821951](https://wordpress.org/support/topic/acfe-is-not-defined-error/#post-13821951)
 * I’ll include a compatibility fix for users with 5.8.x versions in the upcoming
   patch!
 * Have a nice day!
 * Regards.
