I've got Civisualize running very nicely on an installation of CiviCRM 4.5 and Drupal 7 with some custom templates and queries. I then moved a copy of the whole site across to a different server under a different URL. After a bit of fiddling around, everything is now working under the new server/URL, except for Civisualize. I can access the dataviz template pages but no graphs/data are displayed.
Any suggestions as to what to try next?
