There are problems when editing the site, but at the moment I am using the plugin ‘Ultimate Addons for Beaver Builder’ when I have it active, it does not let me edit the site, but when I deactivate this plugin, if you can edit it!
It is for this reason that I ask for help, I already have the newest version for the plugin ‘Version 1.35.3’ and still continues to present problems, but only in two specific sites, ie the entire project can edit the other pages, without any problem!
Both your sites have the exact same jQuery fatal error in the browser dev console and that error is most likely breaking any other jQuery like the builder.
