at first thank you for your great plugin.
Runs fine on local apache installation with php 5.4.4. But on webserver wich runs php 22.214.171.124 after save on the settings page i cant add, modify or even have a look at the markers and layers list.
If i try to look on the list i got an "HTTP/1.1 500 Internal Server Error". "You don't have permission to open page"
Hope you have any suggestions thanks.
