Map locations disappeared

Hello,

I successfully installed this plugin with 10 markers, never had an issue. Somewhere along the lines (possibly from a WordPress update) the markers disappeared. No changes were made to the settings.

Do you have any suggestions why this happened?

I checked on 3 different browsers and they all displayed the same.

Regards,

David
