Icons not displaying

Hi all,

First off let me say thank-you so much for making this amazing software. Everything is going great but I have just come across this issue and wonder if anyone else has had the same problem.
The icons of my devices are not showing up in the default traccar interface. I have checked the logs no errors etc but on the front end I can see

For some reason can't display the svg all of a sudden. I am using the latest version no customisation and SSL

Do you have a URL to check?

yes https://app.webtracker.co.nz/?token=ScQuRKqbJllcLR39EI4hDsYHGfy5T7Wc

weirdly that link I can see the icons - but not logged in as admin

Cleared cookies tried different browsers etc

Icons work exactly the same way no matter what privileges your user has.

Thanks Anton, Not sure what caused the issue but it seems to be back to normal now
