System.Web.HttpUnhandledException Errors in System Log

After upgrading to, we start to see System.Web.HttpUnhandledException errors in the system log. There are many of them every day. 

Does anyone have the same issue before? What could be the cause(s) of this error and what is the possible solution?

Hmm, what cart version were you upgrading from? What other information is being shown for the Unhandled Exception?

Was upgrading from Oh, I forgot there is detail for the error. Here is what it says:

Page URL:/ProductReview.aspx 
Message:Content controls have to be top-level controls in a content page or a nested master page that references a master page. 
Stack Trace: 
at System.Web.UI.MasterPage.CreateMaster(TemplateControl owner, HttpContext context, VirtualPath masterPageFile, IDictionary contentTemplateCollection) 
at System.Web.UI.Page.get_Master() 
at System.Web.UI.Page.ApplyMasterPage() 
at System.Web.UI.Page.PerformPreInit() 
at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) 


Hmm, is the aspx and aspx.cs of that page latest? Seems like old? If it's the Admin page, shouldn't it be  productratings.aspx  instead of  productreview.aspx?
I just found out that it's the powerreviews files. I think it stops working after we upgraded to version
OK, I would recommend contacting them or if needed, we could make that page compatible with MSx for you...
We just decided to stop using powerreviews and want to use the built-in rating system instead. Thanks jsimacek.
