Hola foreros y maestros del php, hace rato tomé un codigo llamado last rss, el código al subirlo a mi web
http://manganimemas.com me trae los ultimos posts de mi blog de blogger (el cual no dejo por que me hace la vida muy facil) y funciona bien pero me lanza un notice
Notice: Undefined offset: 1 in /var/www/vhosts/manganimemas.com/httpdocs/lastRSS.php on line 155
no cacho la verdad el problema, ya revise esas lineas, se supone que el aviso lo da cuando tomamos valores de un array que no existe, entonces puse el archivo en mi localhost, y ahi no me dice nada, verifiqué el display errors de mi php.ini y esta en On asi que no entiendo el problema, soy bastante novaton, alguien podría hecharme un cable, dejo el código de last RSS por si quieren checarlo, si no pues no se apuren, seguro puedo hacer algo pero ya me duele la cabeza.

Bueno vi que se puede deshabilitar el php notice, no se que tan bueno sea, pero no parece muy malo :S
