WHMCS WP integration


Quite new to all this stuff so here I am with my problem. A few days ago I set my WP site with specific theme. No prob. Everything went okelidokeli. My next step was installing WHMCS. The same good old okelidokeli.

So then I thought "Well, there should be somebody out there who wrote a plugin to integrate those two" and that's when I came across this site.

Installing the plugin: no prob at all. Things seem to work just fine, but here's the prob.

It seems like quite a huge bit of template's css is being ignored which makes the integrated whmcs look ... well ... awful.

Does anyone have any pointers on how adjust this and where to do this?
