Errore PHP

Perché ogni volta che entro nel pannello di controllo di invision board mi da questo errore?

IPB WARNING [2] opendir(): open_basedir restriction in effect. File(/forum/upload/) is not within the allowed path(s): (/membri) (Line: 186 of /sources/admin/ad_index.php)
IPB WARNING [2] opendir(/forum/upload/): failed to open dir: Operation not permitted (Line: 186 of /sources/admin/ad_index.php)

forse ho sbagliato la path?

è /membri/*tuonome*/ giusto?

vanno editate le conf nella cache del mysql :) risolto
