the problem is after I publish my webGui application and then show me this message: "403 - Forbidden: Access is denied. You do not have permission to view this directory or page using the credentials that you supplied."
what I have to change in the webconfig to make runnable this app?
Check if you set the handlers rights, you should have one handler for *.wgx pointing to
Concerning the Error 403, try to check if you can see a simple .html file, maybe it is a folder permit and you have to enable IIS service to be able to read it.
