Well, if 4.x has a class called VB, then yeah, that is going to cause issues because I named the class VB in the loader. You could try renaming my class and then editing every instance of:
PHP Code:
VB::instance()->
To:
PHP Code:
NEW_CLASSNAME::instance()->
And any instance of:
To:
PHP Code:
new NEW_CLASSNAME;
I guess I should rename this class in the next version, but just have no time for it now.
