We just recently added a Layout to one of our flexible field entries and it also broke our site. Most of the data isn’t accessible now from those layouts. I removed the layout I added and it didn’t resolve the problem. I restored the site from a backup, tried it again, and again, it broke the flexible fields. I think the fact that it re-ordered them, might have something to do with the issue because the couple layouts above the one I added are ok, it’s the existing layouts, now below the layout I added that are now gone, both Front end and Back End.
