A frustrating mishap. Did a backup in anticipation of testing a module install. Didn't like the module install so restored to backup.
After restore cannot login to admin. Front and back both have error as follows below. Reviewed the files by FTP. No Lib folder, no JS folder, no Media folder. Other folders are there and the contents appear to be there, but since there are hundreds of files, I've no way to know. Can I just re-install the missing folders?
