In DotNetNuke development when exceptions occured, the only short exception message is shown in the web page.
To see full details, you need to open log page, which is required a few mouse click and round-trips.

I found that for development (in Debug mode) it is more convinient to see full exceptions on the page.

The changes can be done in core DotNetNuke\Library\Components\Shared\PageBase.vb file, function Page_Error,

I've replaced strURL += IIf(strURL.IndexOf("?") = -1, "?", "&").ToString & "error=" & Server.UrlEncode(exc.Message)

to the code

Dim sErrMsg As String = exc.Message
sErrMsg = exc.ToString
sErrMsg = Left(sErrMsg, 1800) 'limit the length to be less then GET limit 2048;en-us;q208427

#End If

While sErrMsg.IndexOf("..") >= 0 '17/4/2006 added

sErrMsg = sErrMsg.Replace("..", ".") 'UrlRewriteModule do not except “..” for security reasons

End While
strURL += IIf(strURL.IndexOf("?") = -1, "?", "&").ToString & "error=" & Server.UrlEncode(sErrMsg)

Alternatively DEBUG  condition can be changed to check if it is Administrator running.

I've posted this as a  suggestion to dotnetnuke support.
