Tracking code installed, not seeing the data

Hello everyone, I installed the tracking code for my website turistickekarty.cz but Piwik is not receiving any data. Could you tell me what might be the issue here?

Oh, wow, now it works. Strange, I tried it several times and debugger was empty and now it’s showing the data. Thanks for your help!
