Yea, it seems that it will not work properly with the latest vBulletin version that supports PHP 7.
It should work if you change all instances of

PHP Code:

parent::vB_DataManager($registry, $errtype); 


to

PHP Code:

parent::__construct($registry, $errtype); 


And the function which contains that call should be changed to __construct since a class can not have a function that has the same name as the class. (For example change function vB_DataManager_Pt_Project to function __construct

I took a quick look and it seems that a bunch of files do this so you might have to apply these changes to multiple files.
