Have you ever tried to go to a SharePoint page in your browser and gotten an error like this?
This screenshot is from SharePoint 2010, but this trick works in SharePoint 2007 as well. View Source on the page and you’ll see additional information down at the bottom, hidden inside a comment. sure, it’s still stack dump gobbledy-gook, but it might be more useful to you than what is showing on the screen.
I may be the last man on earth to know about this one, but I still thought it was worth posting. Tip o’ the bowler to Sean Regan for this one!
