Fatal error with new version 3 and Modern Events Calendar

Hey,

after I updated the plugin to the new version 3.0 I got some strange fatal errors when I used functions of another plugin called “Modern Events Calendar” (MEC). The error also occurred when I used the iCal export function of MEC. Why does “Extensions for Leaflet Map” interfere with such a function that has nothing to do with Leaflet?

Here the stacktrace of one of the occurred errors:

I have now downgraded the version of Extensions for Leaflet Map to the old version 2.2.6 I had in my backup and it works again.
