The more fields plugin does not work very well with Justin Tadlocks Members Plugin.
Whenever i try to remove a capability associated with the more fields plugin for the editor on save the changes are not implemented. I have spoken to Justin about this and this is his feedback on the issue.
This is an issue with the More Fields plugin. The plugin is altering capabilities on every page view in the admin. So, every time you change capabilities with Members, it's immediately reverted by More Fields.
Plugins altering capabilities is not an issue at all. The problem is that it shouldn't happen on every page view in the admin. It should only happen once, which is on the plugin activation hook.
You'll have to pass this info to the plugin developer so he can get it fixed.
Anything can be done on this? I really need more fields access capability removed from the Editor.
