Re: Kako da izmenim rss.php da mi salje u rss prvih 500 karaktera a ne sve...

^{02.02.2011. u 23:51 - pre 160 meseci}

Konačno sam instalirao novu verziju. 3.0.8 Nisam hteo da otvaram novu temu pošto je tematika ista.

Zahvaljujem se još jednom svima koji su mi u predhodnom slučaju pomogli.

Dakle sa novom verzijom ide i novi kod...

Meni treba da ponovo bude učitano u rss recimo prvih 500 karaktera, da se ne prikazuje ono odmah ispod naslova by username

Ja sam pokušao sam ali bez uspeha :(

Kod je nešto vaći....

Code:
