Error 500, ASP.NET, page not working

[arthurk]

Hello, I need some help!! I am not very familiar with ASP code and was hoping someone could help guide me on this.

We have a form on our website, where after you click submit on the form you should be redirected to a thank you page. For some reason, after you submit the form you get an error 500 message.

I am using an FPT to update code. On Internet Explorer, I have already disabled the "show friendly HTTP error message" and get the same code details.

We have a CMS that is capturing the error, this is what it says:

at System.Web.UI.Page.HandleError(Exception e) at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) at System.Web.UI.Page.ProcessRequest(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) at System.Web.UI.Page.ProcessRequest() at System.Web.UI.Page.ProcessRequestWithNoAssert(HttpContext context) at System.Web.UI.Page.ProcessRequest(HttpContext context) at ASP.default_aspx.ProcessRequest(HttpContext context) at System.Web.HttpApplication.CallHandlerExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute() at System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously)

I'm not sure if this is helpful. If anyone can help me locate the problem it would be greatly appreciated! Any assistance will be helpful. For your information, I host my site at asphostportal (http://asphostportal.com).

I know I did not provide a lot of information. Just let me know what info you need. I am happy to share.

Thanks.
