PHP Warning null on post_author

Hello @stevendigital,

Thank you for contacting Rank Math support.

Please make sure that you are using the latest version of our plugin: https://rankmath.com/changelog/

Also, please confirm if the warning appears on a specific post/page.

Looking forward to helping you.

Hello,

To answer your questions:

1. I use the latest version of the rank math seo plugin.
2. The warning message does not appear on a specific page. This log appeared on the debug log. There is no specific action that is atteched to it.

I hope this information help.

Best Regards

Hello @stevendigital,

Please add the following code on line 326 of the file:
/wp-content/plugins/seo-by-rank-math/includes/opengraph/class-facebook.php

error_log(get_queried_object_id());

After doing that, when the error appears again it will also show the ID of the page causing this and then we can pinpoint exactly why that is happening.

Looking forward to hearing back from you.

Ok. I have implemented the error log. I will let you know, as soon as I have the results.

Please keep this ticket open.

Best Regards

Hello @stevendigital,

Sure, let us know once the error gets logged again with the page ID triggering it.

Looking forward to helping you.

Some IDs came up in the error log. One ID was a 404 page (a page that can be set from the theme settings) and the other ID that appears is the cart page.

Also, the error below appeared also for post_content, property “ID”, comment_count, and post_parent :

PHP Warning: Attempt to read property "post_date" on null in /wp-content/plugins/seo-by-rank-math/includes/modules/schema/class-jsonld.php on line 767

The odd thing is that the IDs of the pages that I refer to above are not after these errors but appear around 1000 lines below.

Let me know your thoughts.
