odd, usually the error being rendered would be logged with a better stack trace.Looking for the "Unhandled Error" text I see it used in 3 places, two of them are when an error happens within the logger when logging (so unlikely to be yours), the 3rd is more likely from the exceptionmodule.cs class
//HttpExceptions are logged elsewhere
if (!(lastException is HttpException))
{
var lex = new Exception("Unhandled Error: ", srver.GetLastError());
var objExceptionLog = new ExceptionLogController();
try
{
objExceptionLog.AddLog(lex);
}
catch (Exception ex)
{
Logger.Error(ex);
}
}
However, again it should be in admin->event viewer as a general_exception
As to the possibilities - we accepted a few contributions around localized portal settings that proved problematic - we had to spend a few days debugging them and fixing a number of issues. We were under the impression that we had them all (bar 1 odd edge case with portal templates and content localization in multilanguage settings), but perhaps this is another - might be worth checking vw_portals to see it returns valid values.
