I experienced this issue yesterday on a client’s live site – we tried to update a URL field in a custom options page with a new value and instead of saving the changes, it threw out a 404. The odd thing is that the URL field was working fine in local and staging environments.
Any ideas? Does anybody know if a fix is being worked on for this?
