Thread:Project:Support desk/Problem with installing Wikibase

Hi, I installed Wikibase and now I'm getting this:

[7f540d2c] /wiki/Pagina_principale Exception from line 182 of C:\inetpub\Network\w\includes\Hooks.php: Invalid callback in hooks for SetupAfterCache Backtrace:


 * 0 C:\inetpub\Network\w\includes\GlobalFunctions.php(3995): Hooks::run(string, array, NULL)
 * 1 C:\inetpub\Network\w\includes\Setup.php(573): wfRunHooks(string)
 * 2 C:\inetpub\Network\w\includes\WebStart.php(121): require_once(string)
 * 3 C:\inetpub\Network\w\index.php(43): require(string)
 * 1) 4 {main}

Why?
