Theme does not work… again

Hi. Since the last time when a week ago I had problems with Enfold having to recreate a 10 pages website from a scratch (was not able to save any changes made to pages, quick css, menu, etc.) as restoring database/files did not seem to help, I have encountered same issue today again. At some point theme keeps loading advanced layout editor, or saving changes to the theme. I tried deactivating/removing plugins (I had just one – contact form 7), switching to another theme and them back to Enfold. This becomes an extremely time consuming project for me and I could really use your help to make it work. Thank you!
