Basically I was getting the "Your Save Has Failed" when I was trying to make changes to anything using visual builder. Tried asking host to adjust php.ini as the error states. I deactivated plugins and browser extensions, nothing helped. Finally Marius, my dude! helped me figure out it was the 3rd party layout I was using. Something between the custom CSS the creator of the layout added on the front end plus the server's configuration didn't jive together. So I went section by section, removing each one until I found the culprit.
