Odd, I don't believe its 6.0 related as that text is not contained within DotNetNuke anywhere (not that we would ever create a column like "'if yes please explain)

My first guess would be that someone is trying to do sql injection against your site and messing up their query (e.g. perhaps you have a 3rd party module vulnerable to sql injection) - as most SQL injection is url based I'd recommend checking your IIS logs for that string and for any sql syntax (e.g. select/insert/delete/create) - also please check for obfuscated input using DECLARE

Hi Cathal,
The Error is occuring against the Form and List module 5.1.3 (and thus posted to the Form and List forum). There is a field on the Form for "If yes please explain". I don't think this is any kind of attack as this site is just in development and not released publicly (though if someone had the right URL they could get to it). I assume the Form and List module is not vulnerable to SQL Injection attacks as I assume people like you and Brandon review core modules for vulnerabilities.

aha, in that case a datatable is being built up in code to be later bound to something such as a gridview -it would seem theres an error in the core - i'd suggest added it as an issue at http://dnnfnl.codeplex.com/workitem/list/basic

FnL content gets deseralized into a DataTable in memory. The error message tells you that it tries to add a second column with the same name. 

Please verify in FnL configuration that this is not the case.
