Hi I had a fatal error on my website recently it was down and had a critical error warning. When my hosting support looked into it they found it related to -> hesperahome.com/public_html/wp-content/plugins/wordpress-seo

They disabled the plug in , reset permissions and the site is back online. If I try to enable Yoast I get a php warning. The whole error text is below

[03-Jul-2026 12:03:57 UTC] PHP Fatal error: Uncaught Error: Failed opening required ‘/home/customer/www/hesperahome.com/public_html/wp-content/plugins/wordpress-seo/src/functions.php‘ (include_path=’.:/usr/local/php82/pear’) in /home/customer/www/hesperahome.com/public_html/wp-content/plugins/wordpress-seo/wp-seo-main.php:95

Hi @lucymaddison,

Thanks for sharing the error details. It indicates that Yoast SEO is trying to load the file src/functions.php, but PHP cannot find or open it. This usually happens when the plugin files are incomplete, corrupted, or their permissions are incorrect, rather than being caused by the plugin itself.

Since your hosting provider has already reset the permissions and disabled the plugin, the next step would be to completely remove the existing wordpress-seo plugin directory and install a fresh copy of the latest version of Yoast SEO. This ensures that all required plugin files are present.

Do let us know how it goes.
