#21786 closed defect (bug) (fixed)

remove_cap can't unset a negative capability

WP_User::add_cap() accepts two parameters -- the second decides if a user does or does not have the capability. I.E.:

$user->add_cap( 'foo', false );

means a user will not have a capability that any role otherwise allows.

WP_User::remove_cap( 'foo' ) incorrectly does an empty() check rather than ! isset(), preventing negative capabilities from being unset from a users individual capabilities array.

This makes it impossible to revert negative capabilities without first making them positive, and then removing them.

See: #9128
