No icon and name of vehicle showing on map

I'm using version 3.14 with OSM and the following reverse geoding config, moving away from google geocoding because of too many requests:

<entry key='geocoder.enable'>true</entry>
<entry key='geocoder.type'>nominatim</entry>
<entry key='geocoder.url'>https://locationiq.org/v1/reverse.php</entry>
<entry key='geocoder.key'>***********</entry>

It used to work ok with the google geocoding

Clicking on the vehicle in the left hand list does move the map to the position where the vehicle is, however there is no icon showing.
Also after logging in there is no map with all vehicles.

What am I doing wrong?

I would recommend to check browser console for errors. Are you sure you are using official release without any modifications?

I've only changed traccar.xml to the following:

<?xml version='1.0' encoding='UTF-8'?>

<!DOCTYPE properties SYSTEM 'http://java.sun.com/dtd/properties.dtd'>

<properties>

Good morning,

I removed all existing Java, installed default open-jre, reinstalled Traccar but problem is still there.
No errors / warnings in the log. if i log in I see the map, zoomed in at a location of a device, no icon. Normally i would see all devices shown on the map, now i only see them in the list on the left hand side. Could it be a database corruption?
Are there any other things I could look at?

Hope you can get me on track again ;)

I'm not sure why you are trying to guess something. You need to check browser developer console, as I said earlier.

I was just trying to make sure it was not because of a wrong Java version (oracle).
Checked the web console, got some errors after refresh screen, don't know whether they are related?

As you can see, the problem is in JavaScript. Can I have access to the website to check myself?

Sure..

how can send link without showing sensitive data?

You can send it to support email.

Thank you Anton!!!!,

now solved thanks to your quick and to the point troubleshooting.

One device did not have a proper GPS fix. The coordinates uploaded where non-existing, causing the map and icons not to show. After removal of the broken device, the software acted as usual ('usual' meaning very good...!!!)
