I've been working on a WordPress site for a client, and we installed the WP Google Maps plug-in (version 5.04) during the build.
While limited, this worked fine to block out content for the page where the map appeared.
The client has since directly purchased the Add-on package (version 4.05), and once activated, the map stops appearing.
I've tried deactivating both plug-ins, and switching them on again in order to see if that makes a difference (without the add-on plug-in activated, the free plug-in shows the map again).
I've also tried creating a completely new map to test that there's not bad data in the first map, but that makes no difference.
Having looked through the support forum, could find nothing that directly related to the issue we're encountering. However, I can tell you that when the Add-on plug-in is activated, the following error appears in inspect element:
Uncaught TypeError: Object [object Object] has no method 'dataTable'
I checked the source, and the page is able to find and load both the jQuery dataTable script and stylesheet. Perhaps this provides you with a clue however.
The site is also currently in maintenance mode, to hide it from potential visitors ahead of launch - though this should not affect the plug-in. But it does make it difficult for me to give you access to the site to see it in action for yourself.
We need to go live with this site as soon as possible, so any help/pointers would be much appreciated.
