PHP Warning in error_log for link-template.php

  • Hello,

    I’m using WordPress 6.4.3 and after updating to PHP v8.2 (maybe that’s the cause?) I’m seeing multiple entries in my error_log every day, with the following two lines repeating:

    [10-Feb-2024 12:57:52 UTC] PHP Warning:  Attempt to read property "post_type" on null in /home/xxx/public_html/alexkunz/wp-includes/link-template.php on line 4155
[10-Feb-2024 12:57:52 UTC] PHP Warning:  Attempt to read property "post_type" on null in /home/xxx/public_html/alexkunz/wp-includes/link-template.php on line 4157

    According to https://www.ads-software.com/news/2023/10/wordpress-6-4s-php-compatibility/ PHP v8.2 should be good to go for WP 6.4 though, so I’m not sure why I’m seeing this error.

    Is there anything I can do on my end to troubleshoot this?

    Thanks

    Alex.

    WordPress 6.4 might be good with PHP 8.2, but that doesn’t mean your plugins or theme are.

    Please attempt to deactivate all plugins and switch to the default Twenty Twenty-Four theme. If the problem goes away, re-activate them one by one to identify the source of the problem.

    I don’t see a way to jump to those high hoops with my live website.

    What I find interesting is that the warning isn’t thrown for any plugin, but rather, for WP’s own link_template.php from the /wp-includes directory.

    I don’t know much of the inner workings of WordPress, but how would this be caused by the theme or plugin then?

    Hi @antermoia,

    There has been a PHP version conflict with some of the plugins on your website. Try to downgrade your PHP version one version at a time and check your website to see if the issue is gone.

    If the issue persists, maybe you need to contact your hosting provider to better help you resolve the issue on your website.

    Best regards,
