Hi there i run into this problem I am using Geo my WP Plugin which is important to put the location of my vendor, now when I adding the Latitude and Longitude most of the time it didnt capture or save the data, so i contact the theme author and this what he said
“it’s something wrong with your ajax setup. it goes to page http://spotaprint.com/panel/admin-ajax.php which is not existed. I guess you have some kind of security plugin which is not proper configured and disallow using some ajax functions”
now when I deactivate the Hide my WP, the problem was fixed so it is look like he is correct
