Comment (by david.binda):

 > I'm wondering why there is an array in the GET parameters. Did it work
 like that before? If not (i.e. is this a recent bug), what caused an array
 to appear in the GET parameters?

 The concern raised in terms of this ticket is the PHP 8 compatibility of
 the code. While the code under PHP 7 "works" and "just" produces a warning
 while displaying the author page (ignoring the GET param), under PHP 8 it
 produces a fatal error.

 So it's not the functionality of an array passed to the author GET param,
 sorry for not being clear.
