I did the same thing. Working for a client, I made a reccommendation to move to Powweb (they wanted frontpage extensions for interim). After being with one ISP, I moved and simply these guys are terrible. Their entire mail server that we were put on has serious problems in that we can receive but not send email. It's their mail servers. Also DNS and subdomain redirects DONT work. I also found their admin console (not cpanel) funky. Bottom Line, I have to move the client again, making me look bad for reccommending Powweb and lost time and effort with DNS downtime to move to another. I was going to go with OpenSOurceHost and the only thing stopping me was no FrontPage (understandably but client needs transistion). My recco is don't go to powweb...you get what you pay for and i got the wrong end of the draw on the servers they put us on.
I am doing both Drupal 4.6 and WordPress 1.5 development and design.
It doesn't surprise me that Powweb installed 1.2.2. I mean WordPress is simple enough to install (unlike MT which I've gone off of--install, rebuild, regid-design, and trying to do both self-hosted and hosted platforms, not as open as WordPress community, etc).
