When I try switching from PHP 7.4 to 8.0, I’m getting this error when trying to access the WordPress admin. Any idea what’s up?

Fatal error: Uncaught TypeError: in_array(): Argument #2 ($haystack) must be of type array, string given in /home/user/domains/example.com/public_html/wp-content/plugins/wordpress-seo/src/integrations/watchers/auto-update-watcher.php:183 Stack trace: #0 /home/user/domains/example.com/public_html/wp-content/plugins/wordpress-seo/src/integrations/watchers/auto-update-watcher.php(183): in_array() #1 /home/user/domains/example.com/public_html/wp-content/plugins/wordpress-seo/src/integrations/watchers/auto-update-watcher.php(111): Yoast\WP\SEO\Integrations\Watchers\Auto_Update_Watcher->yoast_auto_updates_enabled() #2 /home/user/domains/example.com/public_html/wp-content/plugins/wordpress-seo/src/integrations/watchers/auto-update-watcher.php(94): Yoast\WP\SEO\Integrations\Watchers\Auto_Update_Watcher->should_show_notification() #3 /home/user/domains/example.com/public_html/wp-includes/class-wp-hook.php(307): Yoast\WP\SEO\Integrations\Watchers\Auto_Update_Watcher->auto_update_notification_not_if_dismissed() #4 /home/user/domains/example.com/public_html/wp-includes/class-wp-hook.php(331): WP_Hook->apply_filters() #5 /home/user/domains/example.com/public_html/wp-includes/plugin.php(474): WP_Hook->do_action() #6 /home/user/domains/example.com/public_html/wp-admin/admin.php(175): do_action() #7 /home/user/domains/example.com/public_html/wp-admin/update-core.php(10): require_once('/home/user/...') #8 {main} thrown in /home/user/domains/example.com/public_html/wp-content/plugins/wordpress-seo/src/integrations/watchers/auto-update-watcher.php on line 183

Hi @nineplanetsllc

Could you please check if you are using the latest version of WordPress 6.0 and Yoast SEO 18.9?

We do know that the Yoast SEO plugin should be compatible with PHP 8.0 but there are still certain instances where we still need to improve compatibility – https://developer.yoast.com/blog/the-2020-wordpress-and-php-8-compatibility-report/

Yes, I’ve checked with the latest releases, WordPress 6.0 and Yoast 19.0.

Hello @nineplanetsllc,

I am sorry about the compatibility issues you are experiencing. Unfortunately, we haven’t yet fully tested the plugin with PHP version 8. The entire WordPress community is still working on it. You can read the https://developer.yoast.com/blog/the-2020-wordpress-and-php-8-compatibility-report/.

For Yoast SEO to run properly, you should have a PHP version of 5.6.20 or higher. In fact, we recommend PHP version 7.3 or above. Before you upgrade to a higher PHP version, check if your WordPress site is ready for it. Read this helpful article to learn how to update your PHP version. Also, your PHP memory should be 256M or greater.

Thank you.

Is the particular error I encountered at least one you’re aware of and working on?

Hi @nineplanetsllc

Could you please perform a conflict check with a default WP theme and only the Yoast SEO plugin 19.0 as the plugin enabled and confirm if you’re still able to reproduce this when switching from PHP 7.4 to PHP 8.0 as the only action? Also, could you check if you’ve enabled or disabled automatic updates for the Yoast SEO plugin?

Often, we see problems occur in combination with another plugin or theme. The fastest way to rule out any conflict, is to deactivate all non-Yoast plugins and switch to a standard theme like Twenty Twenty.

Please test this on your development or staging site, if you have one. If not, we recommend using the Health Check & Troubleshooting plugin. This plugin has a troubleshooting mode, which does not affect normal visitors to your site.

If you’re unfamiliar with checking for conflicts, we’d like to point you to a step-by-step guide that will walk you through the process: How to check for plugin conflicts

I tested disabling all other plugins and switching to a default theme (Twenty Twenty Two), but the error still comes up, so it doesn’t seem like a conflict. And automatic updates are currently disabled.
