When connecting Google analytics, Yandex metrics and email rating, everything went off in an incomprehensible way, please help and recommendations what to do?

Question

Programming

Yo! There was a big problem with my site. I connected Google Analytics, Yandex metrics, email rating and other similar tools, and bang, everything stops working! In the sublime, it shows only zeros. On the site, I tried to roll back to the old version, it hardly worked, now it does not display pictures on the site. And how to say it does not display, it gives them out as if you are looking at them through a broken screen (that is, there is no error in the code, everything is recognized by the browser). It looks like a virus in general, but from where, again, I’m sitting either from a Mac or from a PC on which nod32 has never had viruses. There’s no point in hacking me either, the site is just a portfolio.

I would really like to know what to do in such a situation.
