 * After downgrading from 5.2.2, the backend is no longer working with Visual Builder
   and is throwing errors. I am unable to resolve the errors and need your assistance,
   if possible.
 * I have pictures of the errors but have no idea how to upload them. The error 
   specifically point to jQuery not defined and TinyMCE not defined.
 * Any guidance would be appreciated. Thank you.
