Justin Tadlock 2 years ago The question is a bit too general to answer directly. It depends. For example: Are you building a plugin and want to make certain admin pages available via custom capabilities? Are you wanting to restrict front end access of a plugin’s custom post type? Are you using someone else’s plugin and want to limit access? Something else entirely? In short, I need specific information on what you’re wanting to do. In general, yes, it’s possible to limit access to things. But, sometimes that depends on the plugin.
