Buon giorno, vado subito al dunque, ho preso questi script dal web(ovviamente) sono 4 file.
Quello che non capisco è come mai mi restituisce questi due errori
"Sorry: It's not possible to reach RSS file " e "I give up trying to fetch RSS feed."
quando il file RSS è presente nella stessa directory del file che lo richiama..vi posto il contenuto dei 4 file partendo ovviamente dal primo:
PS:Lo so che è troppo lungo e nessuno ha pazienza,ma magari qualcuno con un colpo d'occhio migliore del mio, individua il problema..
