PHP - errore tema wordpress in

salve, ho creato un tema per wordpress con artisteer che ho comprato ma non mi danno assistenza. uso xampp ultima versione con php8 col php7 non succede ma ho bisogno che funzioni con l' 8... sono un mediocre programmatore php e non sono capace di sistemare l' errore.
l' errore è questo:
