PHP Notice ‘post_type’ of non-object in class-wp-query.php line 4338
-
Hello
I have a lot of the following error in the error log file:Error at PHP version: 7.4
PHP Notice: Trying to get property ‘post_type’ of non-object in ***/wp-includes/class-wp-query.php on line 4338Error at PHP version: 8.0
PHP Warning: Attempt to read property “post_type” on null in ***/wp-includes/class-wp-query.php on line 4338I put the part of the class-wp-query.php file that includes line 4338 below.
public function is_singular( $post_types = ” ) { if ( empty( $post_types ) || ! $this->is_singular ) { return (bool) $this->is_singular; } $post_obj = $this->get_queried_object(); line 4338: return in_array( $post_obj->post_type, (array) $post_types, true ); }I’m getting similar warnings under PHP 8 and also PHP 7.4, with any urls of my website, ending with /feed/;
(the feed link gets displayed, however the warning is at the top of the page – each /feed page)
I’ve searched for that warning message on Google and I can say came up with almost hundreds of websites indexed with that warning message in the results.
So, it seems that’s a very common problem.
The warning appears only in /feed/ pages, the mentioned line in php file contains:
return in_array( $post_obj->post_type, (array) $post_types, true );I’m currently using version PHP 7.4, but I’ve also tested version 8.0
i disable plugings but when i visit this url:https://sonarweb.ir/sonarweb.ir/feed/
error added to error_log file
i install health-check plugin and test all plugins
The errors comes from WooCommerce!
WooCommerce is up to date
Tested at all WordPress version: 5 and upAll my WordPress and plugins and my template are up-to-date
If possible, guide me on what to do.
Thank you very muchThe page I need help with: [log in to see the link]
