Hi @biodust, Sorry for the lack of info, we try to update customers on issue resolution as quickly as possible, however this issue is still open.
One thing that triggers the error with the editor is if there are any emtpy collection lists on the page.
As a workaround, you could duplicate the page, then delete the emtpy collection lists and republish the site.
As soon as there is a fix pushed out, I will let you know immediately.
Thanks in advance
