How to remove the insecure cobalten[.]com domain?

Question

Google

Good afternoon. For the second month I have been fighting with Google AdWords regarding the approval of advertising. They don’t want to approve, because they see on our site “the insecure domain cobalten[.]com''. Unfortunately, our webmaster is on sick leave, so we have to figure it out ourselves. I checked both manually through notepad and on different services - everything is clean, can't find it. Help solve the problem)

Hello!
1) install the Wordfence plugin and crawl the site. It usually finds extra links.
2) It’s not a fact that you will find the name cobalten during a mass search through notapad++, since they are usually encoded in base64 for example ...
3) at first glance, I didn’t notice anything suspicious ... I recommend that you also order site optimization ... otherwise the main one weighs 15 mb, and the number of requests is more than 200)))

Answer 2

regardless of WordPress, the site is slow,
just drain your Adwords budget
