404 and "index not found" errors after upgrade to 6.4.4 in Install & Upgrade Support Posted March 17 Thank you for your help. After trying several things, I also found your earlier reply about getting into admin. Long story short, I don't think everything was updated in the upgrade. Database was still saying 6.4.2. I restored my backup for that and my website came back. I think you are right about me missing the new info, but even when I looked at the files there was no new admin_xxxxx.php file. So anyway, I am going to try again today to upgrade and watch for the 2 links. I will let you know how it goes. Thank you again.
