Cats completely messedup after install version is 184.108.40.206 Beta. I took backup all directory and database then replaced with new version is 220.127.116.11 Beta files in root. then copied attachments, upload folders and config.php file.
then I ran installwizard.php went good. after this I was trying to run migrateextrafield.php getting 404 error. file doesn’t exists there in root also.
