Block access to Wiki

Hi There,

I am using your plugin (free edition), and first of all, thank you for that !
I have an issue and I don’t find solution : I give access to some of users of my website to post articles, but when I give them this access by checking “edit_post” into role administration, I give them in the same time access to wikis, but I don’t want these people to see (and manage) the Wikis contents.

How can I do that to block them ?
If I need to buy the premium version, no problem, but I want to sure to clear out this problem.

Thanks !
