Discussione: Problema installazione vbulletin 5.2.2

Buonasera dopo essermi scervellato per qualche giorno non riesco ancora a trovare soluzione....
Il mio problema e' il seguente collegandomi al forum http://francescocappuccio.it/forums/
e volendo accedere al pannello di controllo admin mi riuslta questo messaggio di errore http://francescocappuccio.it/forums/admincp/
Vi posto il file .htaccess perche' googlando in rete mi pare di capire che sia quello il problema.:

< IfModule mod_rewrite.c>

# comment on the following RewriteBase line and change it to match your folder name.
# This resets the other mod_rewrite rules for just this directory
