Currently running EE v2.5.2 (Build Date: 20120606) and I’ve had installed EE Forum 3.1.7 and the issues where even as a super admin I couldn’t post a thread. Updating to the new 3.1.8 (20120507) puts me in the same situation. I do the usual forum upgrade with the core EE update at the same time, same problem I’ve had since installing it earlier. Have tried various themes just in case something went awry but still no banana. How do you tell where the issue is lying with the Forum module?
