https://example.com/advert-author/xyz/ not displaying

Hi,
what do you mean by not displaying? The page shows a 404 error, a white page or something else?

If you are seeing a 404 page, please try going to wp-admin / Settings / Permalinks panel and click “Save Changes” button to reset WP router this should fix it.

If you are seeing a white page, open wp-config.php file, add there a line define( “WP_DEBUG”, true ); and refresh the page it should show an error message which you can copy and paste here i should be able to help then.

If something else then it would be best if you could describe the problem in more details.

Thank you here it is

It is not a 404 page it is a white page

Thanks for the details, the white page is usually caused by some fatal error, the errors you listed above are just notices and they will not cause a white screen.
