Your site doesn’t include support for the Themify Builder block.

Dear all,

I am using Themify Ultra in a website, it used to work properly in the past. I perfirmed a backup a few months ago, and website is not working after I restored it. I got the following error messages. I uninstalled and installed again the plug-in and theme but it is still not working.
If I use another theme is working well, however I built many pages in my website with this Themify Ultra theme so I am trying to solve it.

“In this case, WordPress caught an error with your theme, Themify Ultra.”
