Chrome shows warning on the main page only:  "your connection to this site is not fully secure". Is this a problem of my content or there are issues in the template? Also yoast plugin shows warning that my main page can't be indexed by robots. But my robots.txt is ok.  I appreciate if you can help me with my problem. I can grant access to all files to check the problem

I solved the problem with the secure alert. My map marker was loading from dev.petrovka3.ru instead of main domain
