1.- Install the component.
2.- Go to your PHPmyAdmin.
3.- Click on the table "jos_periodico_nueva_noticia".
If you see on the top of the page a text similar to the one below, InnoDB is installed. If not, you should ask your hosting provider to install it for you:
"InnoDB free: 11264 kB; (`FuenteRSS`) REFER `joomla15/jos_periodico_rss`(`IDRSS`)"If your provider installs you InnoDB after you installed the component, you must reinstall the component to get it work fine.
