I am going to guess here but I think you have a permissions issue. I registered at your site and I see two problems. First is a registered user can only see about three forums. None of which can be opened by a registered user un less they subscribe. When I try to subscribe I get a error that I did not select a payment method but none are offered. When I visit my feeds none of the forums are there to view except for the basic three PM , recent topics. recent posts. They don't work either because I don't have access to the forums. So I think it is a permissions issue that since I have not paid for membership it is blocked by a permission issue.
And by permissions issue I mean by the group management options in the control panel not the file permissions.
Blue Man Group There is no such thing as stupid questions. Just stupid answers
I only have a few test forums up until I get all the bugs worked out and I open this to our network. And it's true that the forums will only be able to be read after a subscription has been purchased. (The purchase option is being repaired by Rick).
I'll look at the permissions, but am not sure how the permission settings would result in a Parsing error?
