Instead of a form with fields, these errors in the pop-up box:

#0 unknown:unknown ErrorException("preg_match(): Compilation failed: unrecognized character after (?< at offset 3")
#1 /app/SurnameTradition/PatrilinealSurnameTradition.php:32 preg_match()
#2 /edit_interface.php:2393 newChildNames()
#3 /edit_interface.php:519 Fisharebest\Webtrees\print_indi_form()

Has been suggested a rogue ~ (tilda) in a name somewhere, but nothing like that found so far.
