eval()'d code on line 5 in functions.php errors

[Lynne]

This is line 1259 of functions.php:

($hook = vBulletinHook::fetch_hook('fetch_userinfo')) ? eval($hook) : false;

So, you have a plugin using the hook "fetch_userinfo" that is causing the problems. You need to figure out which plugin, then go read the modification thread and see if a fix has been posted for that error.
