Hello long time i use piwik and me two sites work perfectly with them.
Now i use matomo and one site (joomla) statistics works fine, but second site (WP on https) i only see some bots entries and dont have real time statistics.
There is nothing wrong with the file, but https://matomo.zespol-atlantis.pl doesn’t have a valid HTTPS certificate, so browsers refuse to connect to it.
So you need to use something like Let’s Encrypt to get a HTTPS certificate and set it up correctly.
If I understood correctly, the problem is that there is no ssl certificate in the domain.
If I move matomo installation to a second domain where I have this certificate purchased (for subdomains should work) it will then display the statistics correctly?
But I can’t find the Tracking code on the page. Can you check the third tab in WP-Matomo (“Wlacz Sledzenie”) to check if you have enabled that WP-Matomo adds the Tracking Code.
