News ticker is displayed before the_content()

open this file:
wp-content\plugins\news-ticker-benaceur\news-ticker-benaceur.php
and replace this code:

//[wp_news_ticker_benaceur_short_code]
	function shortcode_ntb_func(){
	  return wp_news_ticker_benaceur_();
    }
	add_shortcode( 'wp_news_ticker_benaceur_short_code', 'shortcode_ntb_func' );
//[wp_news_ticker_benaceur_short_code]

with:

//[wp_news_ticker_benaceur_short_code]
	function shortcode_ntb_func($atts){
		ob_start();
		news_ticker_benaceur_post();
		$content = ob_get_contents();
		ob_end_clean();

	    return $content;
    }
	add_shortcode( 'wp_news_ticker_benaceur_short_code', 'shortcode_ntb_func' );
//[wp_news_ticker_benaceur_short_code]

The problem was solved, only update the plugin now
