My client is suddenly having trouble connecting to a website using Contribute. They are getting the following erroe message:
If the IP address or the server name got changed this error message will appear.
These values are stored in the cthub file in the server under _mm folder, when there is a mismatch this error message will be thrown.
1) You have to go ahead and remove the administration settings and re-administer all the settings back.
2) FTP to your server and manually change the older ip address value to new one in the cthub***.csi under _mm folder inside your website folder.
