Hostupon's one-click install script works pretty good, all except the forums (Orca) link. This page come across with some of the markup echoed out to the page. I asked them about it and here was the response:
-------------------
Our shared/reseller service supports Dolphin. Orca and RMS (Ray video chat) are not supported on shared hosting.

It looks like Orca requires Dom/Xlst which is a component for php that is only available on our private hosting.
--------------------

Just a heads up see more to those of you who are having the same troubles that I am. So my options are 1)don't use the forums or 2)purchase private hosting.

Hostupon seems to be great from a support, one-click Dolphin install, and reseller package perspective, but it'd be better if Orca would work too. Anyone know of a different host that has it all?
