Hi Gaurav,
Yes I've been through the guide and I've used the php diagnostic and there is a problem with the sql settings. I've been in contact with godaddy support to try and sort the server side php settings, they have done what they can but are out of ideas. I'm sure with godaddy being one of the major hosting companies that this has been tackled before. Do you know what the php settings should be for muse forms to work?
