The UBB itself is a web script; the assumption when downloading it is that your webserver is configured properly to allow php scripts to run; it's not within the scope of the ubb to hack at settings in the php.ini as it should run with the default settings that come with php (at least when rolled out from a webhost); if a server isn't configured properly to run php scripts it's more a webhost issue vs a ubb issue...
In any case, I'm glad that you got it all sorted out.
