Imagine rang

[Sufletel]

Cum pot pune imagine la rangul din legenda?

[atomik]

NU stie nimeni ...? mar interesa si pe mine

[bogdan]

Incearca MOD-ul [RC] Group Icons

[Sufletel]

Nu am inteles cum fac sa apara Group Icon!
http://www.autinhyeu.com/img/images/137 ... _thumb.png

[bogdan]

Ai facut modificarile cerute de MOD? Probabil ca trebuie sa pui pe FTP niste imagini pentru fiecare grup.

[Sufletel]

Am pus un folder cu imaginile in images/
Dar totusi..pe acel site nu este un tutorial..fiecare sa plans de o problema din cate vazusem!
Acolo sun doar puse niste imagini,si folderul cu imaginile pentru grup!

[bogdan]

Probabil ca trebuie sa cureti cache-ul forumului. Vezi apoi daca iti apar. Daca nu intreaba in subiectul deschis la phpBB.com

[Sufletel]

Okey..va multumesc! o sa le cer un tutorial!

[Sufletel]

Deci am facut rost de tutorial..dar dupa ce am terminat..imi da 3 erori la 3 fisiere:
1. la index.php
Parse error: syntax error, unexpected $end in /home/hosting/.../index.php on line 156
