As DanBred has moved their servers, you must change the server name on your local installation of PigVision. Go to General - Administration - Settings. In the window that opens you have to open "Layout setup" and add the columns "Dan bred upload" and "Server", click "Ok". In the Server-column you have to change the server name to "ftp.danbred.com", as in the picture below:
Then click "Ok" and your changes will be saved.
