Forum Can't access the Home tab
 

I just moved my site to a new hosting provider and I'm still encountering some bugs. I am able to access all of the tabs across the top bar, except the home tab. For example,

Forum: http://www.immigration-information.com/forums/forum.php
Blogs:http://www.immigration-information.com/forums/blogs/
What's New: http://www.immigration-information.c...e=vBForum_Post

But if you go to the Home tab http://www.immigration-information.com/forums/content/ you get a 404 error.

Can anyone spot what I have done wrong and suggest how I can fix it?

Thanks
