So I have cloned my 1.7 installation onto a new server and it works fine. Per upgrade instructions, I uploaded the 1.9.3 files to correct folder and did not overwrite my "ost-config.php" file. When I try to log in to start the upgrade, I receive an "unable to authenticate" message. I am using the same db and everything is working fine under 1.7 so I do not understand why it can't authenticate me. I have tried to delete the ost-config or change the name on ost-sampleconfig but that will prompt the installation wizard. Any guidance would be greatly appreciated.
