I am having an issue in that Display Geo Distance has stopped working.
It does work if I enter something in the 'Near' search box which is not pre-populating.
I have just updated to latest versions of Display Geo Distance and Vantage and still won't work.
I have installed on 3 sites, one uses a child theme; http://sallinsbusinessassociation.com/
The other 2 don't.
and a clean install to test stuff.
The only plugins installed on this site are AppThemes Updater and Display Geo Distance - Nothing else and a clean Wordpress and Vantage install.
BTW, when it does work it is very slow.
