If all plugins are deactivated and a standard theme is activated, the message is probably caused by an incomplete and/or incorrect data record in the database. It is difficult to say which one this is. You could take a look at which data records you can edit in the backend (pages, posts) and whether anything is displayed incorrectly there.

Since the messages are “only” notices and not real errors, you could also ignore them by deactivating the error output in wp-config.php.

I just backed up date so i can edit post　no white page come up.

but still template error shown hopefully wait for proper wordpress version

There will be no update for this, as this is a bug in your data that was probably caused by the theme or plugin you used previously. You are welcome to try to report this as a bug: https://core.trac.www.ads-software.com/ – but you will probably get the same answer there as here.

If your issue is related to Trac 51565, you could:

1. Go to Appearance and then Menus.
2. Check each menu item in the selected menu to ensure that it is complete and that it does not include any removed posts.
3. Click the “Save Menu” button after you have verified the menu’s accuracy.
4. If you have more than one menu, switch to the others, verify their accuracy and save changes.
5. Return to Customize to find out if the post_status notices still print.

If that still does not remove the notices, I recommend changing WP_DEBUG to false in wp-config.php to hide notices and errors.
