global.php(29) is hook global_start. VaultWiki doesn't use this hook. You would have to look at the other products you have installed and see what uses this hook. You probably had errors hidden before, which is why you believed your site had "zero bugs". You can hide the errors again, but they will still be there. In
vault/config.php, find:
Code:
@ini_set('display_errors', 1);
Replace with:
Code:
//@ini_set('display_errors', 1);
If you have problems with the Beta release, though, hiding the errors will make it very difficult to debug. In general, fixing errors is advisable to hiding them.
In vBulletin 4.2 the wiki doesn't use the Wiki NavBar Tab Position setting anymore, since there is a more powerful option available. The setting is for earlier vBulletin versions. To disable the tab in vB 4.2, you should use AdminCP > Settings > Navigation Manager, and uncheck "Active" for the Wiki tab.
For the Configuration error, are you using vBSEO? If so, make sure you made changes to your .htaccess like so:

But only if you have set vbseo.php as the VW_DEFAULT_SCRIPT in
vault/config.php.
