Having spent 2 days coding my own content access module, I've managed to grant along with Organic Groups the intended set of permissions to my users.
Thing is, that authenticated users who now have edit grants on nodes, when they press the "Edit" tab, they can only edit the node's title!
Did a print_r in my form_alter for that form and it seems all form elements except for the title have their #access set to FALSE.
Any ideas on what might be going on here? I mean I can set it to TRUE in the same function but instead of repairing the problem I'd like to correct it.
