Checked myself – it is compatible.

Thank you, works like a charm! ??

I have a problem with the code, not with installing a plugin.
It’s not required, so I don’t know why I have to use one. Also, I’m stubborn ??

For other people with similar problem, here is the functions.php with properly functioning Google Analytics in header:

Just put your ID instead of XX-XXXXXXXX-X.

For displaying it in the footer, just change wp_head to wp_footer.

Thanks, but I don’t want to use plugin.

Thank you very much! ??
