Same here. Can’t save anything.
After attempting to save a new snippet, I see the “saved” banner at the top, but I get a blank snippet form. If I return to the list of snippets, it’s not there.
I have tried to save changes to an existing snippet, but that too doesn’t seem to save changes. I get the save banner at the top of the content area, but no changes are saved to the DB.
I have manually added a record to the db, and that will show in the list of snippets properly. However, changes to this cannot be saved from the admin.
The solution posted by billras101 worked great. Thanks!
