An error has occurred.

For detailed error information, please see the HTML source code, and contact the forum Administrator.

As I am new to Jforum, I cannot seem to figure out the reason behind the error.Still trying to debug the error.
P.S. The forum topics I am trying to access already have quite a few posts in them,i.e., they are not empty/null.

Any help here would be greatly appreciated.

Someone asked this yesterday. Let's continue discussion in that thread so as not to duplicate conversation.
