SPD 2010 can not connect to SharePoint
I got this error when I tried to open the site in SharePoint Designer 2010. SPD is installed on the client.
The server could not complete your request.
An error occurred while trying to fetch data from your SharePoint site. Unexpected response from the server. The content type of the response is “”. The status code is “OK”.
The reason is that there can only be 1 binding on a web application. If you have more than 1, it will no longer work and you get this error.
One possible solution is to extend your web application (central administration – application management – manage web applications).
If you open the site of that extented web app, SPD will connect to that site again.
