Map not Showing up on Front Page Stick Post

I have a post sticky’d on my Front Page containing my travel map so that it is is always the first thing my visitors see. This was working great until I noticed a few weeks ago that the map was no longer displaying. If you click on the link to the sticky post, the map displays as normal on the post, but it will not load on the Front Page. I’m not sure if an update to this plug-in or an update to WordPress that caused this or if there is some other issue Any feedback or ideas would be much appreciated. Thank you.
