We are using Godaddy Wordpress Managed Hosting and while building the website we keep receiving “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.” when editing in Cornerstone. It will allow us to change a single element setting and then it freezes with the error when trying to continue with other changes.
We’ve tried turning off all plugins, switching from child to parent theme, turning off Godaddy’s object caching and disabling WP_CACHE, increasing the memory limit, there is no customized JS - nothing seems to be working.
We are using the most recent Pro theme 6.6.3 and running PHP 8.0 and WordPress version 6.7.2
We are really struggling to figure out what is wrong.
