Problems after upgrade, not sure if Vbulletin or vBadvances is the problem

[Designer]

Hi guys/gals,

I upgraded my forum to 3.5 today and after checking that it was right upgraded vBadvanced to suit, after the upgrade most things work except for some reason online users and buddy list no longer are working from the portal, works ok from the forum.

It seems to be linking to:

http://www.performancextreme.com/online.php?

this just gives a 404 error, but i suspect it should be linking to http://www.performancextreme.com/forums/online.php?
as my forum is in the /forums directory

this is the same with buddy list, at the same time, my avatar on the forum has disappeared only to be replaced with a missing image, even tho the file actually exists. Do you think something went a little wrong on the vbulletin upgrade or can i correct this in another way?

Many thanks

EDIT:--

Avatar problem was fixed by reverting the postbit legacy template, other modules problem still remain

Edit your buddy list module and make sure you have this for the 'Module Link' option:
{$vbulletin->options[bburl]}/profile.php?$session[sessionurl]do=editlist

Then edit your online users module and make sure you have this for the link:
{$vbulletin->options[bburl]}/online.php?$session[sessionurl]

As for the avatar problem, can you view the properties of that image and post the URL it has here?

Cheers for the quick reply Brian, the Module links are exactly the same as the one's you mentioned. But still getting the same 404 page not found.

Are you positive? The URL's between vB 3.0 & 3.5 are similar, but do require a small change in 3.5. There's also no other reason I'm aware of that the links would not work if you have what I posted above.

my bad lol, they were there just missing the parenthesis, working fine now.

Thankyou Brian, you're a star :)
