I have used wordpress source code for many of my projects. Recent projects have been updated with bugs in the admin page with the message as below:
Notice : add_submenu_page is called incorrect . The seventh parameter passed to add_submenu_page()must be an integer, representing the menu position. Please see the Debug Guide in WordPress for more information. (This message was added in version 5.3.0.) In /home/giayctbn/public_html/wp-includes/functions.php on line 4970
I have tried for many different projects on different hosting. But the error is the same. Hope someone sees this note and supports me.
