Internet Explorer affected by current Basemap.js file

Hi Anton,

When using current traccar-web source code the map view is affected when using IE. Just showing a small blue area in the left top corner. In Chrome and Edge it is working fine.
Please test on your end and advise.

What's the error?

Hi Anton,

Below is what I get on IE.

What version of IE?

Internet Explorer 11

Looks like the problem is with the ol-layerswitcher library.

Thanks Anton,
