Apparently the problem is with the theme, and now it has been solved.
Thanks very much.
Hi,
Thank you for the reply.
i’m not using any extension plugin, i’m just using the core Meta Box plugin, that problem only occurs on version 5.4.8. when I downgrade it to version 5.4.7, then the problem goes away
I only tried both methods, and it worked
thanks, that’s very helpful
