After last update plugin doesn't work

Can you give us a URL where that is happening?

Yes, I can: https://soundaround.me/en on block “THE WAY AROUND THE WORLD”

Seems like either your host or one of your other plugins doesn’t like the “name” parameter in the map URL. So this map will not load:

https://soundaround.me/?geo_mashup_content=render-map&map_data_key=07772161df783c5abbcb813d40dc8672&lang=en&map_content=global&height=400&width=992&zoom=2&center_lat=9&center_lng=151&load_kml=https://soundaround.me/wp-content/uploads/2013/08/Around2.kml&name=gm-map-1

but it will without the name parameter:

https://soundaround.me/en/?geo_mashup_content=render-map&map_data_key=07772161df783c5abbcb813d40dc8672&map_content=global&height=400&width=992&zoom=2&center_lat=9&center_lng=151&load_kml=http%3A%2F%2Fsoundaround.me%2Fwp-content%2Fuploads%2F2013%2F08%2FAround2.kml

I’d try deactivating other plugins next to see if this behavior changes.

Ooooo! It is interesting! Do you know how to cut this parameter? Because I don’t use it in my code.

<?php echo GeoMashup::map('map_content=global&height=400&width=992&zoom=2&center_lat=9&center_lng=151&load_kml=https://domain.com/wp-content/uploads/2015/01/map.kml'); ?>

Now I know that conflict with plugin “Hyper Cache”.
I just made disable “Use readfile()” and maps start working again.

resolved

Thanks for reporting back, I’ve also shared this information here:

I understand, that disabling “Use readfile()” is not desire of a problem.

Yes, problem in plugin “hyper cache”. Only “Cleaning all cache” helps me or deactivating plugin. Cleaning helps only once.
