Map showing blank
using 18.104.22.168 - url: http://partner.staging.wpengine.com/karte/
I've checked the data.json file - that's the only one which I can't set to 766 due different other reason - but why need the plugin write permission - I update the file manually ... and data.json are filled - but could see no map?
Please take a look at the url - and instruct what to do
thanks in advance
