I get this error on the following thread: https://www.flyertalk.com/forum/brit...-greeting.html

Error: ArgumentCountError: 7 arguments are required, 6 given in ..../includes/functions.php on line 3127

I can get to page 1 of the thread by clicking on the title, but if I click on first unread then it mulls for 10 seconds and then I get the error above. It's the only thread which has the problem as far as I can see. I also tried to use Go to Page at the bottom, input page 90 (which is where my first unread post is located) and I get the error as well.

It's the same on Edge on Windows (desktop) and Chrome on Android (mobile). It started this morning (GMT) for me, but I didn't read much yesterday.
One in incognito, the other logged in, same result.

(Also, it isn't great to show verbose errors on prod servers, but that's just my 2 pence).
