Issue: Double URL's when clicking links

Hello,

I have vaultwiki installed at www.bayoujeepersoffroad.com/main.

I have no issues clicking the wiki link on the nav bar and it pulling the page up. However I do have a problem when I post a new wiki in the Default forum wiki it then shows up the " Recent Treads" on the main page.

The only issue I have is it does this hwen you click on one of the links in the "Recent Treads" area.:

http://www.bayoujeepersoffroad.com/m...d+to+be+ lower

It adds the site url twice.

how can I fix this.
Thanks,
Nash
