I think I've found a bug. I use Types plugin to create/manage Custom Post types http://wordpress.org/extend/plugins/types/.
When I go to my CPT settings at Adminize, I deactivate "HTML Editor Button" at CPT for some user roles.
Setting this option deactivates HTML Editor at CPT only for the default Editor Field. But any other custom fields - Editor fields with Visual/HTML editors are not affected by the setting - HTML editor is accessible when logged in with the user name that should be affected by the Adminize plugin, even though it has been restricted at its settings.
I also found that the default Editor field is not hidden at CPT when I deactivate it at Adminize's settings - it is still visible when logging it with user role that should be affected by restrictions. However its HTML editor tab can be hidden.
Any workaround, please?
