Installed the plugin but gets fatal error during activation… Fatal error: Cannot redeclare sar_remove_x_pingback_header() (previously declared in /volume1/web/wordpress/wp-content/mu-plugins/disable-xml-rpc-pingback.php:35) in /volume1/web/wordpress/wp-content/plugins/disable-xml-rpc-pingback/disable-xml-rpc-pingback.php on line 35 Checked disable-xml-rpc-pingback.php on line 35 & found this… add_filter( 'wp_headers', 'sar_remove_x_pingback_header' ); function sar_remove_x_pingback_header( $headers ) { unset( $headers['X-Pingback'] ); return $headers; } Wordpress is installed on virtual host via WordPress app on Synology web server running at home. I’s new to WordPress but do I really need this (must use) plugin per WordPress & how without getting this fatal error? This topic was modified 8 years, 5 months ago by Anonymous User . Hi, That error is indicating you that you already have the plugin installed as a mu-plugin in /volume1/web/wordpress/wp-content/mu-plugins/ So you don’t need to install it from the Plugins page. Only one instance of the plugin can be enabled. Regards. Ok, thanks.
