I get "ArgumentCountError: 5 arguments are required, 4 given in ..../includes/functions.php on line 3127" anytime I start with the link to last post in a thread, then try to go back a page. It's not possible to scroll up from the last page in a thread. Nor is it possible to jump to the next to last page using "Go to Page"

Also, if I like 1 post in a thread, like the 1st one in this thread, the system will not allow me to like any others.

Desktop or mobile? MacBook

Reproduced in multiple browsers? Which do/don’t work (we at least need to know the initial browser)? Safari

Steps to reproduce the issue Happens in every thread now, at first it was just the Secret Santa thread

Reproduced on incognito mode/private window? N/A

When did this problem start? November 28, yesterday

Addendum: I am now getting the same 3127 message when I try to access a thread (Stocking Stuffers, Women Travelers forum) by 1. clicking on the last post link, 2. clicking on the thread title from screen listing Travel & Dining forums and 3. from within the Women Travelers forum.

Something else I noticed recently, but prior to the 3127 problems is that from within a thread, I used to be able to click on the name of a forum, for example, in "Support&Services Technical Support and Feedback November 28th PHP 8 Update Bugs" I could click on "Technical Support & Feedback" to go back to the list of threads in that forum - the subforum names are no longer links and can not be used for navigation.
