Despite not changing any of the code on my user profile for ~ 1 month, the text-

"Warning: mysqli_fetch_row() expects parameter 1 to be mysqli_result, string given in /www/subeta.net/include/class/database.new.php on line 277"

appears at the top of the page and nothing can be clicked/interacted with on the profile (https://subeta.net/users/POURRITURE). The font has also changed.
