Hello, I have a custom post type installed and cannot seem to allow low level users the ability to assign terms (categories) to posts. I've read other forum posts on this but I can't seem to make sense of them. The post author cannot select any of the "categories" since they're all grayed out. I'm using Role Editor and also tried Capability Manager to create capabilities but I'm missing something. The last bit I tried was to enable anyone who can read assign terms. What am I missing? Thanks so much!
'capability_type'=>tcb, 'capabilities' => array('assign_terms'=>'read'),
