  • Resolved timlumsden


    Hi everyone,

    Hoping someone can help! I’ve updated Yoast SEO to 14.1 and I’m getting a fatal error:

    An error of type E_ERROR was caused in line 506 of the file /home/website/public_html/wp-content/plugins/wordpress-seo/wp-seo-main.php. Error message: Class ‘WPSEO_Register_Capabilities’ not found

    Has anyone encountered this before and does anyone know how to fix it?

    Hi @timlumsden @kaptelneha23

    We apologize for any issues that you may have encountered when updating the Yoast SEO plugin. We’d like to try and help you get this sorted out.

    Can you confirm you’re using the latest version of WordPress 5.4.1 and that all of your other plugins and themes are up to date? Could you also let us know if you updated it using the WordPress admin dashboard or if you used another tool or method? Did you update from v13.5 TO v14.1, or did you update from v14.0.x to v14.1?

    Could you please try to follow the steps below and see if you are able to update the plugin successfully:

    Hi, the update also caused a fatal error.
    WordPress 5.4.1
    Everything up to date.
    Upgrade from 14 to 14.1 from the desktop
    PHP 7.4 (change doesn’t help).
    New wordpress-seo folder uploaded.
    Only disabling the Yoast SEO plugin solves the problem.

    @tonydomrep, If you need support then per the forum guidelines please start your own topic.

    A lot more people will see your post, and that way you stand a good chance of getting the assistance you want. Despite any similarity in symptoms, your issue is likely to be completely different because of possible differences in physical servers, accounts, hosts, plugins, theme, configurations, etc. Thus one problem, on one setup is not indicative of the functionality and reliability of an application as a whole:

    I’ll be archiving your post and mine to not spam the original poster and detract from their question.


    Thank you @marcanor
    Problem solved 😉
