I have questions and events plugins activated (along with several others)
However, I seem to have isolated a fault to be:
When Questions is activated it displays the list of 15 questions at http://tradr.com/questions/
Then, when I activate Events+ it forces the user to the same URL but a particular question page.
No-one can see the list of Q's or ask a Q.
Also, there seems to be intermittent Internal Server 500 issues and a generally slow response from the server when both are active.
I only have 1 events listing with buddypress active and the buddypress sub plugin activated (not groups).
PS: I will try to do some debug reporting shortly.
