I have a problem with SharePoint 2013. I have created a WSP package that works great on 2010 but doesn't on 2013.
Actually, when I tried to access to the page, I receive the classic "Unexpected error has occurred" with a correlation ID attached.
The problem is that at the specified correlation ID I get only:
As you can see this contains no exception or failure neither High / Unexpected rows in the log.
I tried to check the Event Viewer: no error. I tried to check the IIS log files: no error. I tried to enable the classic ASP.NET view for errors: doesn't work.
How can I handle this problem without knowing which problem is? Does somebody experienced something similar?
Is there any other way to debug SharePOint operations? Actually I tried to enable as "verbose" level the information I get doesn't help me.
Why did I get the exception page if there is no exception traced?
The ASPX page I tried to access is under the _layouts folder, could this (in 2013) be a problem?
