I have pro and have 2 problems:
I made a 404 page with leadpages and it changed my home page to the 404 page. I deleted it and now I have this on my home page and cannot edit it in pro 5.08 Wordpress 5.8.1 This is what it says when I try to edit it [[[The preview could not load due to the iframe response being incomplete. This is most often related to a plugin conflict or customizations introducing a PHP error. Orgin URL https:// changeyourbeliefsnow.com Preview URL https:// changeyourbeliefsnow.com/ I have deactivated both leadpages plugins as well as Super Cashe. It did not help.
A few of my pages were made in Pro, but I can only edit them in Cornerstone.
I would like to either get my home page back or I can rebuild it if necessary. I do not have a backup to help me. I could really use some help.
