Thank you!
I tried to switch off all the plugins but that didn’t help.
It looks like the issue itself is not coming from WordPress but Chrome, and I since fixed the bug: Chrome thought that it no longer supports overflow x hidden property.
This has prevented jquery from running.
Now I have another issue: Chrome Developer Tools misinterprets my <head> contents into <body> but opening source (not inspect) shows correctly.
I was trying to add favicon and it doesn’t show in Chrome but Firefox works perfectly.
Any ideas? Anyone else having similar problems in Chrome?
Thanks!
