We had an issue with a 3rd party extension and had to do a backup restore. It was from a VM and should have been as simple as pointing it to an earlier snapshot. However, now I'm getting caching issues. I ran static content deploy and that fixed some of it.
Im getting errors like the one below. Also some products won't let me save images.
