I have been following a tutoral on webparts here: http://www.codeproject.com/Articles/337551/A-Beginners-Tutorial-on-ASP-NET-Web-Parts
And followed it example and copied the code across into my default.aspx, everyone was working until I modified the webpart headings and then ran it, at that point nothing from the web parts showed on the page at all. I undid my changes and tried again, now I can't get the webparts to show at all. I did the tutorial again, completely refreshing everything but nothing will show.
I have tried to do a simple test by adding some from the toolbox but as you may have guessed, when I run it they do not show.
