Regular users don't see Wiki under their Dashboards

Hi, I was having trouble with Wiki Lite, which was that Wiki Editors couldn't see the pages they had created, so I decided to buy the paid version. I deactivated Wiki Lite and activated Wiki. Now users can't even see the word "Wikis" under their Dashboards. However, now if I deactivate Wiki and reactivate Wiki Lite, Wiki Lite works correctly. But I want Wiki to work since I paid for it. What should I do? I have already deactivated all of my other plugins.
