@footbananas,
Can you please tell me what OS you’re using when you see this? Off the top of my head, you might try clearing cache/site data for youtube and see if the issue persists.
@footbananas,
You’re right, you did! My bad – thank you for answering anyway
I’d like to check a couple things here:
Can you please try visiting Youtube in a Private browsing window and test to see if live chat works as intended there?
Can you please go to (in a normal/standard Window) youtube, visit a channel with live chat active and when you get the error, open up the Console in the dev tools window and share any output you see there (a screenshot of the output would be sufficient)? (Menu --> More tools --> Developer tools --> [Console])
Those errors are coming via an extension chrome-extension://jfempmidaeihapfgebideoelfjgnegab which is Phlinx Browser Extension Uninstall this extension and try again
