MyBB Community Forums

After installation, I went through all the configuration settings and changed some of them to my preference. The problem is that I can post topics, but I cannot read/view threads. When I click onto a thread to read, it has the page where it reads "you haven't been activated or don't have permission to access this page." I have looked over all group permissions and I don't know what the problem could be. It is strange. Any help would be appreciated. Thank you.

Double check user group settings, also check the permission settings for that forum. With the forum permissions you may need to click edit/set permissions next to the user group to get the setting you need.
