    Dear,

    The site has been down with a critical error message.

    WP : Latest
    Buddypress : Latest
    Yoast Plugin : 17.8

    Debugging showed that the error occurs as soon as we activate the Yoast plugin, and dissapear when we disable the login. Trying to re-install the plugin did not fix the error.

    On apache logs we see the following (I have hide the real links as this is a public forum):

    AH01071: Got error 'PHP message: PHP Fatal error: Uncaught Error: Class 'WPSEO_Frontend' not found in /var/www/vhosts/*hided_domain*/httpdocs/wp-content/themes/aardvark/lib/inc/buddypress-functions.php:125\nStack trace:\n#0 /var/www/vhosts/*hided_domain*/httpdocs/wp-includes/class-wp-hook.php(303): ghostpool_remove_bp_wpseo_title()\n#1 /var/www/vhosts/*hided_domain*/httpdocs/wp-includes/class-wp-hook.php(327): WP_Hook->apply_filters()\n#2 /var/www/vhosts/*hided_domain*/httpdocs/wp-includes/plugin.php(470): WP_Hook->do_action()\n#3 /var/www/vhosts/*hided_domain*/httpdocs/wp-settings.php(578): do_action()\n#4 /var/www/vhosts/*hided_domain*/httpdocs/wp-config.php(87): require_once('/var/www/vhosts...')\n#5 /var/www/vhosts/*hided_domain*/httpdocs/wp-load.php(50): require_once('/var/www/vhosts...')\n#6 /var/www/vhosts/*hided_domain*/httpdocs/wp-blog-header.php(13): require_once('/var/www/vhosts...')\n#7 /var/www/vhosts/*hided_domain*/httpdocs/index.php(17): require('/var/www/vhosts...')\n#8 {main}\n thrown in /var/www/vhosts/*hided_domain*/httpdocs/wp-content/themes/aardvark/li...', referer: https://www.*hided_domain*/christopher/media/

    Ayone has a idea?

  • There are a few threads about this. I’m guessing they changed the naming a little and anyone (like me) is finding their websites broken. I’d revert to an older version until they fix it.

    Hi @madicom,

    The WPSEO_Frontend class has been deprecated since version 14.0 of our plugin. In version 17.8, we completely removed it. If any code tries to access that class, it will throw a fatal error.

    Looking at your error message, it looks like your theme aardvark is trying to access this removed code, which results in this fatal error.

    To prevent this error, you will have to disable that theme and / or reach out to the maintainers of that theme to make them aware of this issue. You can also provide them with this link with the current alternatives for the WPSEO_Frontend class.
