Help Me!!!

Hi guys I'm new here and I'm already fascinated by all the information available, I have one question though, I have installed the CPA lead gateway on my WP site but the problem is it is not loading on the main site, if I visit the post links or the post themselves it works fine, but it wont load on the main site, the site that WP is installed on, can anybody help me with this it is slowing me down, is there anyway I can get it to load when someone visits the url that WP was installed on?
