Hi @nikish,
What I’m saying is duplicating your home page as a template as a backup (you’ll see that I already saved it in the template named X TEST), then import it to another site ( staging ) for testing, deleting each element. You don’t have to edit your actual homepage in your live site.
And you can also edit existing elements through skeleton mode, like in this screenshot

And this issue is due to internal server error, and not because of the builder. It can’t load the request as the server respond with an internal error. It will happen to any builder affected by host environment issue.
And yes, it’s the folder I checked and there was no debug.log, so perhaps there is something in your host like caching that prevent changes to take effect instantly.
And the debug.log has no error so this is probably content related since it’s being triggered within the callback of jQuery.js
. That’s a browser script so it shouldn’t trigger the error unless the host trigger it intentionally due to content (security).
Is there a way we can continue the troubleshooting in a staging copy of your site? I like to disable everything while troubleshooting and can’t do that since it’s live.
Thanks!
