It tells you the problem: The directory or file specified does not exist on the Web server.

Use the trace rule to figure out what is going on. It also tells you how to do that.

yes i know but the file exists on the server because i checked on my ftp.

the problemm is very strange because this happens when i change something from the .aspx example delete a textbox remove a range validation etc.

Does the website is hosted on shared hosting? Does it works if you revert back to older version?

[domingo]

yes it is hosted on mochahost, if i revert to older version of my .aspx yes, but for some reason even if i add ex label it will give me this error :/

Normally this error will occur if the server was unable to understand the request. Will you try by prefixing www?

Are you compiling the new version in a different framework than the one which you created the application?
