install.php Functionality Blocked by Webhost

... the web server (LiteSpeed) ...

I'm all for using minority solutions where they're a good fit, but a proprietary webserver, together with its own implementation of PHP (from what I can gather from their website), is surely asking for trouble.

Is there any reason for not using something more mainstream? Is there some anticipated return on the time investment necessary to get it working?

Just curious.
