I've been using the DNN Q&A module for a while.  Just recently it stop displaying unanswered questions.  When clicking the link,  the URL gets changed from "/questions/view/browse/type/questions/unanswered/true" to "http://myelectrical.com/questions/def/errormessage" and the module just displays all the questions.

I've had a root around to see if I can find the issue, but I'm stuck.  Any help will be appreciated.  A copy of the event log follows:

the message suggests one of the unanswered questions has some data that is causing a binding problem -typically you would attach a debugger to identify the failing entry and then update it in the database (as well as updating the code to ensure that future questions can't add corrupt data)

I would suggest maybe doing some direct queries into the database tables that store the question information.  Its possible that the question is either really long and might be corrupting the way its stored or contains some code or markup that is causing the display engine to crash.

Thanks for the answers so far.

I've not idea how to attached a debugger - so I've not be able to investigate that. I have spent an hour or so querying the tables and seeing if I can spot anything. No luck.

If anyone has any other suggestions it wold be great.

I've spent so much time trying to resolve this, and I'm getting nowhere. If anyone can point me in the right direction or give me some clue as to what SQL is being run to extract the unanswered questions, I may be able to get somewhere.
