Check boxes not accessble and visible to the Web interface.

Hi,

I'm using the Traccar 3.14 version.
The checkboxes are not accessible and visible, at any place on the web interface.
I tried Safari, Edge, IE, Chome, and Firefox browsers, all are with the same response.
You can see the problem at Link (Remember Checkbox)

Please help me to make them accessible and visible.

That's not Traccar.

I am sorry, I am not getting your point.

My point is that you are not using official version.

I downloaded the Traccar 3.14 and hosted to own server with some modifications. Is it making it non-official?

Of course it does. Have you tried on non-modified version?

It was working before the modifications, Modifications are mostly CSS customization into Web folder.
Now getting your point.

What are the ways or chances that I'll be helped for my topic to non-official Traccar version?

If you want to customise Traccar I would recommend creating a theme instead of changing CSS:

Thanks a lot for your time, I'll try with what you recommended.
