Title: Plugin update causes fatal error Last modified: September 15, 2022 --- # Plugin update causes fatal error * Resolved [damiendoherty](https://wordpress.org/support/users/damiendoherty/) * (@damiendoherty) * [3 years, 8 months ago](https://wordpress.org/support/topic/plugin-update-causes-fatal-error-3/) * Hello We are unable to update the Yoast plugin beyond 19.1. Doing so crashes the site with fatal errors like this: * ``` [Thu Sep 15 12:19:28.064975 2022] [proxy_fcgi:error] [pid 1537094:tid 139771976308480] [client 192.168.0.152:34296] [114.119.146.51, 127.0.0.1] AH01071: Got error 'PHP message: PHP Warning: include(/home/public_html/wp-content/plugins/wordpress-seo/vendor/composer/../../admin/class-yoast-notification-center.php): failed to open stream: No such file or directory in /home/public_html/wp-content/plugins/favorites/vendor/composer/ClassLoader.php on line 412PHP message: PHP Warning: include(): Failed opening '/home/public_html/wp-content/plugins/wordpress-seo/vendor/composer/../../admin/class-yoast-notification-center.php' for inclusion (include_path='.:/usr/share/pear:/usr/share/php') in /home/public_html/wp-content/plugins/favorites/vendor/composer/ClassLoader.php on line 412PHP message: PHP Fatal error: Uncaught Error: Class 'Yoast_Notification_Center' not found in /home/public_html/wp-content/plugins/wordpress-seo/wp-seo-main.php:466\nStack trace:\n#0 /home/public_html/wp-includes/class-wp-hook.php(307): load_yoast_notifications('')\n#1 /home/public_html/wp-includes/class-wp-hook.php(331): WP_Hook->apply_filters(NULL, Array)\n#2 /home/public_html/wp-includes/plugin.php(476): WP_Hook->do_action(Array)\n#3 /home/public_html/wp-settings.php(461): do_action('plugins_loaded')\n#4 /home/public_html/wp-config.php(105): require_once('/home/...')\n#5 /home/public_html/wp-load.php(50): require_once('/home/...')\n#6 /home/public_html/wp-blog-header.php(13): require_once('/home/...')\n#7 /home/public_html/index.php(17): require('/home/...')\n#8 {main}\n thrown in /home/public_html/wp-content/plugins/wordpress-seo/wp-seo-mai...', referer /category/stories/page/3/ ``` * I see lots of others having issues with updating the plugin too.

First, can you let us know what WordPress and Yoast SEO versions you have? Also, are other plugins and theme updated? * Thread Starter [damiendoherty](https://wordpress.org/support/users/damiendoherty/) * (@damiendoherty) * [3 years, 8 months ago](https://wordpress.org/support/topic/plugin-update-causes-fatal-error-3/#post-16037928) * Hi [@maybellyne](https://wordpress.org/support/users/maybellyne/) We’re using PHP 7.4 Yes all other plugins and themes are updated. Any ideas? * Many thanks * D * [Jeroen Rotty](https://wordpress.org/support/users/jeroenrotty/) * (@jeroenrotty) * [3 years, 8 months ago](https://wordpress.org/support/topic/plugin-update-causes-fatal-error-3/#post-16055087) * Hey [@damiendoherty](https://wordpress.org/support/users/damiendoherty/), * Thank you for your reply and patience. * Checking your initial error stack, I see it references a file but fails to do so: “No such file or directory” – that lets me think that the installation or update just failed and not all files were extracted successfully. * If you download our latest installation file on [https://wordpress.org/plugins/wordpress-seo/](https://wordpress.org/plugins/wordpress-seo/)– and upload that to your Dashboard > Plugins > Add New > Upload plugin – and confirms to proceed the installation and replace your current version of the plugin, does it work then? * Thread Starter [damiendoherty](https://wordpress.org/support/users/damiendoherty/) * (@damiendoherty) * [3 years, 8 months ago](https://wordpress.org/support/topic/plugin-update-causes-fatal-error-3/#post-16057778) * Hi [@jeroenrotty](https://wordpress.org/support/users/jeroenrotty/) Thanks for getting back to me. Yes I’ve tried that and reinstalled all the files several times and still get the same issue. * Many thanks * Damien * [Jeroen Rotty](https://wordpress.org/support/users/jeroenrotty/) * (@jeroenrotty) * [3 years, 8 months ago](https://wordpress.org/support/topic/plugin-update-causes-fatal-error-3/#post-16057826) * Hey [@damiendoherty](https://wordpress.org/support/users/damiendoherty/), * Thank you for your reply, sorry to hear that. * However, looking again at the first error stack, it might be related to a plugin conflict between our plugin and the “favorites” plugin you are running, as seen in the error – referenced to: * wp-content/plugins/favorites/vendor/composer * Is that plugin updated and well maintained? I have a feeling that the plugin has some code that references our plugin but on an old file or location in our plugin and that fails to work. Can you temporarily disable the “favorites” plugin and see if Yoast SEO then runs as normal? * [Jeroen Rotty](https://wordpress.org/support/users/jeroenrotty/) * (@jeroenrotty) * [3 years, 8 months ago](https://wordpress.org/support/topic/plugin-update-causes-fatal-error-3/#post-16068128) * This thread was marked resolved due to a lack of activity, but you’re always welcome to re-open the topic.
