I am trying to open a SharePoint website "http://qasite.organization.com/SharepointSite/". But I am getting the following error in Sharepoint Designer as follows,
Could not find a web server at "http://qasite.organization.com/" port 80. Please check to make sure that the web server name is valid and your proxy settings are set correctly. If you are sure that everything is correct, the web server may be temporarily unavailable.
But the web server http://qasite.organization.com/ is available. Other sites on the server are working fine. After clicking "OK" button on the alert box, another message appears as,
An error occured while trying to fetch data from your sharepoint site. Unexpected response from server. The content type of the response is "". The status is "OK".
How to solve it?
