Deep flush

Hi,

on a community, people can purchase a "membership" which gives then an access to a blog and a content type. The membership is linked to a role, and the role gives access to permissions (add blog, add content type).

Recently, a member has lost his access to the content type, but still can add blogs.

Clearing the cache did not solve this problem, neither rebuilding the permissions. I was told about a drush command (drush cc "module list"); but I'm not shure that I want to "dive" into Drush.

Is Cleaner an equivalent of this Drush command? Can Cleaner help me perform a "deep flush" of cache?

Thanks.
