Our site is moving towards https before October 2017. Some of our pages are using
gothere.sg map but I have seen warnings of rendering nonsecure images. Can help to make sure that those static images be served over https, as well? Even in the example,
https://gothere.sg/api/maps/examples/basic-map.html, when you inspect and check the console, you will see the warnings. Hopefully this can be resolved soon on your end as that will be good : )
