Existing galleries disappeared after upgrade and editing produces 404's
I read the instructions and thought I followed them. It led me to believe that I only needed to overwrite the old files and all would be well but not only are the galleries messing and have no images but it's giving me 404's on pages when I see they are there in the FTP. My client doesn't like that this has happened to his live site and I need to get it fixed asap.
