I see that the plugin still uses the old user levels, this has been depreciated since 3.0.
I have a custom user role called 'clients' and I would like them to be able to user the order function.
I've tried with the members plugin, to give them access to it, but it doesn't work.
Anyway this can be done?
Edit: I've managed to show the menu by editing line 420 of post-types-order.php so it doesn't use the userdata_get_user_level() function, but instead locked it to one capability. This isn't ideal though, I imagine.
