Hello Grzegorz,

You can find the Site Details tab at the bottom of the comment textarea (see the attached screenshot).
The information you enter there is private, meaning that only I can see it.

Regarding the issue with the icons - you have either figured it out or it is an issue caused by your local environment (browser extensions, cache and cookies, ad blockers, ISP configuration, firewall, etc).
I am not able to reproduce the issue. Here, have a look at this video that I recorded for you.
For test purpose you might try on another computer.

I don't know how it is possible that there are icons in the video?? . The problem is not solved. I wrote to the hosting company and they claim that there are empty spaces, they didn't see the icons and they didn't help.

I just tested your website on another computer, with another internet provider. The icons were shown properly.
Then I opened your website on my phone (again, tested it with two different internet providers). The icons were shown properly again.

It is simply not possible to troubleshoot an issue that I cannot reproduce.
Anyway, please make sure that you have applied the fix from this discussion and also make sure that you read all the comments there.
