When I try to save some edits using the CSS Edit module 1.3.1 I get a 403. The URL looks like it points to a non-existent file: Legacy Winchester
File permissions?
The URL doesn’t need to match up with a file exactly, that’s not really how URLs in Omeka S work.
What level of permissions does your user have?
Global Administrataor
It seems to be functioning OK now. Probably malformed css. Thanks for your efforts.
