#300 mysqli_num_rows(): Argument #1 ($result) must be of type mysqli_result, bool given

From Debian Bullseye to Bookworm, Mariadb changes from 10.5 to 10.11. And lots of other things too.

GnuSocial did not survive the change. The web interface is visible, but instead of the usual posts and things, all that I see is this message "mysqli_num_rows(): Argument #1 ($result) must be of type mysqli_result, bool given"

Anything I should change?

It looks like this is because Bookworm comes with PHP 8.2

GnuSocial is for PHP 7.4+ (but not 8.2 ).
