Here’s the issue Chris, I’m surprised I didn’t spot this before.
I paid for the PRO plugin and have it installed on my sites. When I get work the plugin needs updating and I update via the WordPress dashboard, it updates to the most recent version of the FREE plugin. Mashups aren’t included in the FREE version so it the shortcode doesn’t work. Is it possible to make the PRO version update through the dashboard?
Thanks for your help on this.
