I, too, am having trouble getting wordpress to work properly on L4rge.com.
I have a wordpress blog set up on another host and it works, but L4rge is another story. I don’t buy that there is something wrong with wordpress not working, I think it’s on the end of the host.
There is an option to install wordpress directly from L4rge. If you go into your cPanel and scroll to the bottom, there is button that says “Site Software”. Clicking that brings you to a page with the option to install WordPress – but in my experience it doesn’t do ANYTHING.
Perhaps you can try your luck. If nothing else works, hopefully somebody on here can bring us the fix.
