Parser Error Message: Could not load type 'cheats.WebForm1'
The fact that you are having this error and no webform1.aspx[\b] page is the real problem.
You must have renamed a webform1 into default.aspx and forgot to do some things before deploying:
1) assign default.aspx as your starting page, sometimes the IDE deletes this value from the proper property (known bug in vs.net).
2) when you rename a file, make sure your class name has the same name of the file.
WebForm1.aspx
class WebForm1.aspx
This would cause an error:
default.aspx
class WebForm1.aspx
and be careful, default in the.net framework is a reserved word therefore when you rename the class of your default.aspx page make sure it has a '_' before (or after, I can't remember)
recompile the solution and then redeploy your application.
Good Luck
