It took me all damned day, but I managed to finally get a working install of WordPress v.2.3.3 on the test subdomain. I tried installing it manually, using first one installation guide and then another. Neither installs worked. Then, I stumbled across Installity. Success!
I’m so relieved that I might cry. This has been thoroughly frustrating.
Now, I need to try to upgrade the test install to v.2.5.1. If that’s successful, my plan is to import my blog to test, back everything up, then wipe the main blog entirely and re-install from scratch, using the same process as I did on the test subdomain.
It’s awkward–and time-consuming!–as hell, but since my web host isn’t being very helpful (and they only support version 2.3.3, anyway), I’m not sure what else to do.
I can think of about a million other things I’d rather be doing this weekend.
