Hmm, I'm wondering if it's because the new site doesn't have an actual domain pointing to it yet, and is only being referred to by IP address. (http://xxx.xxx.xxx.xxx/wiki). Perhaps everything is set up OK and when I actually move the domain over things will start working on their own. I can always hope.

I can confirm your error as duplicated and I didn't move hosts... I upgraded to PHP 5.3.0, so that's where the issue is coming from. My backtrace was slightly different, but very close:

Internal error

Detected bug in an extension! Hook vBSSOAutoAuth failed to return a value; should return true to continue hook processing or false to abort.

NoeJeko: I know it's unsupported, but any help would be appreciated, as I was totally loving this!

Found this on a Mediawiki support site from someone who was complaining about a similar issue with other extensions:

This happens when the callback expects an argument to be passed by reference but this argument isn't passed by reference when calling wfRunHooks(). These extensions are being fixed (ConfirmEdit should already be fixed), so try to download the latest for the extensions causing these errors and see if it's fixed. iAlex 08:13, 13 September 2009 (UTC)

If I comment out the AuthPlugin_vBSSO extension, the Wiki will load (but I have no access to edit)...

Fixed!!

Apparently, PHP 5.2.x used to auto-convert value passing to reference passing, but 5.3.x won't and it errors out. Very simple fix.

Line 264 of includes/AuthPlugin_vBSSO.php:
Replace

function vBSSOAutoAuth(&$user) {

with

function vBSSOAutoAuth($user) {
