I ran the migration toolkit to move my small project from K13 to Xperience by Kentico. When I go to edit any of the pages in Page Builder it brought over, it throws an "An error has occurred. If the problem persists, contact your system administrator." message. Viewing the page on the website it looks fine. If I recreate the page from scratch to look exactly the same, there are no errors when I got back and edit. This happens on every page I brought over I try to edit. There are no errors in the log. Any ideas where to look?
Did you update any of your code? The migration tool only migrates the data.
