hai,
I used FCKEditor in my Application. But when i browse the server any time i get a error window. And the Error as follows:

The resource cannot be found.
Description: HTTP 404. The resource you are looking for (or one of its dependencies) could have been removed, had its name changed, or is temporarily unavailable. Please review the following URL and make sure that it is spelled correctly.

Requested URL: /SchoolAdmin/fckeditor/editor/dialog/~/fckeditor/

How Can I fix this problem.

Thanks in Advance,
Sreevidya
