unlock tables error when user com_connector.

[Hanoifishing]

Hi all!

I'm using com_connector to integrate my cms with vbb. I have tested it with login, addUser. Login function is ok, but addUser is failed.

I have error in function.php:

Call to a member function unlock_tables() on a non-object in ***\forum\includes\functions.php on line 5771.

I have debuged it, $vbulletin is null when exec_shut_down is executed. How to fix this problem. I don't want to edit original vb code.

Please help me. Thanks in advance.
