Hi Mike,
First of all, thank you for all your work on the portal!
Today I installed the latest version of the portal (v1.6.0) on our forum (v4.1.15). Before we had v1.5.3.
However, I have encountered following issue:
Everything works fine until I set the portal as the default application. When I do this both the 'portal' and 'forum' links in the 'browse menu' lead back to the portal. I couldn't find a solution, so now I have put temporary the forum as the default application and then both links are behaving normal.
Do you have any idea what could be wrong? We didn't have this problem with v1.5.3 of the portal.
