The Plugin “Header Footer Code Manager” has been removed

Any further information on this? I see ‘Critical’ mentioned a lot but no real detail.

Fatal error: Cannot declare class Hfcm_Snippets_List, because the name is already in use in /var/www/vhosts/domain.com/httpdocs/wp-content/plugins/99robots-header-footer-code-manager-master/includes/class-hfcm-snippets-list.php on line 0

Update the zip file and change:

99robots-header-footer-code-manager

to

header-footer-code-manager

Then when you upload it to your site it will say the plugin already exists and asks if you would like to replace it with the new plugin.

The error you are seeing is because if the folder name is different then it adds it to your site as a second plugin. So you’ll have HFCM installed twice. That’s why the class name is already in use.

this is the uninstall.php of this plugin.

<?php
// If uninstall is not called from WordPress, exit
if ( ! defined( 'WP_UNINSTALL_PLUGIN' ) ) {
	exit;
}

$option_name = 'hfcm_db_version';
delete_option( $option_name );

// Drop a custom db table
global $wpdb;
$table_name = $wpdb->prefix . 'hfcm_scripts';

$wpdb->query( "DROP TABLE IF EXISTS $table_name" );

this will drop the table when the plugin is deleted.
