The remote server returned an error: (404) Not Found.

Recently, I ran across a new error that I had never seen before.





First of all, this message is very misleading as it is returning a 404 error (which traditionally would mean that the file that you are requesting is not there or is not available), however this is NOT the case and your default.aspx page really is safe and sound. This error is very similar to pretty much any .NET error that you run into in SharePoint, and so is the resolution.



The Fix…

The fix is to simply close the misbehaving web part. You can do can accomplish this by adding "?contents=1" to the end of your web part page.

Example:

http:///default.aspx?contents=1
