I recently noticed that the maps in some of the forms aren't displaying, instead there is a empty space. What is interesting is that the map in one of the forms is working just fine, while in the other two forms it's not. I've reverted to default twenty-twelve theme and disabled all plugins other than wpuf. I've tried creating a new form, and previewing the form (i.e. from the wpuf admin page) however nothing seems to have an effect, and only the one map on the one form works. To show you I have created a couple of pages with one working and one non-working map field:
Any tips would be great, please let me know if you would like admin access to the site.
