I use the forum theme and quote a post, it's doesn't work. Than I open the BB code plugin , it's OK! However when I quote a post which already had a quote message, it can't be shown correctly!Just like below

[quote=amember][quote=bmember]first quote messages[/quote]
amember had somewords here...[/quote]
bmember now have somewords here...
