Help me with my VBadvanced

I jus installed vbcms on my forum.
The cmps_index.php is installed in root folder
and vbforum is installed in a sub-folder.
and also renamed cmps_index.php to index.php in root folder.

The vbcms home page is perfect but wen i clik any forums from homepage, my links are becoming lik this.

Plz help me, wat do i have to do or edit which file ?

P.S: Also, my images in the cms homepage r not appearing, wen i update the image paths thru install, its perfect but wen i save the options the page is blank

 

Did you edit this line in cmps_index.php (now index.php)?
$forumpath = '/home/public_html';
