[ Closed ] [parser bug] wrong quote brakes forum layout

If using wrong quote like the one bellow, it can mess up forum layout. The bbcode warning message did not expect this, so it validates and gets published

Here's what happens

code used was this

(quote=some_user
some random text.(quote)
some more random text(/quote)

On my forums this happened when some one was quoting already quoted text and forum denied the posting. The user then changed some code and was able to post the message, that eventually messed things up
