Code:
<html><html>Our system is currently busy at the moment. Please try again later. (XXX.XXX.XXX.XXX)</html></html>
when you visit the site. Take a look real quick in your root and see if there is an index.html present. If so, rename it to index.html.old and see if that resolves the problem. If that solves it, you need to set up so that you serve the index.php before the index.htm/html.
