Hello,
I understood everything you wrote.
The problem is, however, that both websites are 100% identical = with the same The7 Theme template, the same plugins, the same version of WordPress, …
In other words, the website “wpbakery.renad.sk” is a 100% copy of the website “blog.gtowizard.com”
The website “wpbakery.renad.sk” was created only to demonstrate what happened after the upgrade from 4.24.1 to 4.24.2
If I now return the old version 4.24.1 to the “wpbakery.renad.sk” website – it will appear fine – I have already tried that.
