Note:

This problem has been resolved since module versions 15.06.08.


If you cannot update the module, the following files must be edited to resolve the problem:

  • app/code/community/Netsearch/OPS/Model/Observer.php
  • app/code/community/Netsearch/OPS/controllers/Adminhtml/OpsstatusController.php

In both files this code line can be found:

return Mage::getSingleton('admin/session')->isAllowed('sales/order/invoice/create');

 

It must be changed to this:

return Mage::getSingleton('admin/session')->isAllowed('sales/order/actions/invoice‘);
