I am new to this group. After I installed YOAST SEO plugin i'm getting this error message "Fatal error: Call to undefined function apply_filters_deprecated() in /home/ipzen/public_html/wp-content/plugins/wordpress-seo/admin/menu/class-admin-menu.php on line 246" i cant find the plugin in cpanel as well. Help me solve this problem
Access your server via FTP/ SFTP , or a file manager in your hosting account’s control panel (consult your hosting provider’s documentation for specifics on these), navigate to /wp-content/plugins/ and delete wordpress-seo plugins.
Delete Plugin via FTP as metioned earlier in this thread. Install the newest WP-Version and reinstall the plugin. It should work !
