Suddenly my Attributes Controller not working v1.3.9h

Using v1.3.9h
When im using the Attributes Controller and want to give a product some Attributes and click on insert,
Zencart is going to the index of my admin and no Attributes are connected tot the product.

Hope somebody can help me

Thank you !!

I put a back up of attributes_controller.php back to the admin dir and now its working but doent know what the latest attributes_controller.php
was doing

I think its was when i putt in the module wholesalepricing when it went wrong

In the zip file are
attributes_controller.php that one was not working but has the dualpricing mod
And
attributes_controller.phpbak10a this one is working again but without dualpricing

Attributes controller is different from 1.3.9h to 1.5.x

Its both for 1.3.9 ...
