I have installed a community module Mass Edit for v6.1.

The strange thing is the menu item is only visible for the user administrator.

I have an other user with as far as I can see the same rights as the administrator. The menu item is not visable for this user.

When I try to install the specific menu item via user interface etc. I get the error:

Operation prohibited by access rules, or performed on an already deleted document (Operation: create, Document type: ir.values).

The module installs on the right side menu entries. These entries are visable for the normal user. But if they are executed I get the error:

AccessError You can not read this document (mass.object) ! Be sure your user belongs to one of these groups: /.

Any suggestions?
