 * Hi [@blarney27](https://wordpress.org/support/users/blarney27/),
 * This is an error coming from one of your snippets. You have an array and are 
   trying to access the `['name']` key, but that key does not exist.
 * Unfortunately, it’s not something I can fix in the plugin, but if you’re able
   to find the snippet causing the error and post the code here, I’m happy to help
   debug. Searching for `name @line:3` might help.

 * Thank you for the follow up, much appreciated. I only have one snippet; here 
   it is:
 * function remove_page_from_query_string($query_string)
   {if ($query_string[‘name’]
   == ‘page’ && isset($query_string[‘page’])) {unset($query_string[‘name’]);$query_string[‘
   paged’] = $query_string[‘page’];}return $query_string;}add_filter(‘request’, ‘
   remove_page_from_query_string’);

 * Hi Kevin,
 * Here’s how you could rewrite that snippet to prevent errors:
 *     ```wp-block-code
       add_filter( 'request', function ( $query_string ) {
       	if ( isset( $query_string['page'], $query_string['name'] ) && 'page' === $query_string['name'] ) {
       		unset( $query_string['name'] );
       		$query_string['paged'] = $query_string['page'];
       	}
       	return $query_string;
       } );
       ```
