The Bebuilder blocks Classic and Gutenberg editor
I have already encountered a problem when I was unable to save information when I entered the Bubilder through the Classic editor. But I got out of the situation by using Gutenberg editor.
But as it turned out, the problem is much broader.
I installed the Popup maker plugin. But could not create a window.
None of the editors showed up.
After that, I turned off all the plugins, except for it, and the editor did not appear.
But after that I switched to another default WP theme and a miracle, the editor appeared!
Of course, you can suggest me not to use this plugin, as it is not compatible with your theme. Another plug-in for creating pop-up windows, which I also tested, is also incompatible.
But! When I try to create a post using Gutenberg or the Classic editor, I also fail to do so.
I see a list of blocks, but I can't add a block to the page
What solutions can you offer?
