All my topics is weird formatted on my forum

So my forum has been down for quite a while, but recently ive decided to have it reopened. There's a problem where all my topics is wrongly formated.

An example of this would be:

• This is how it should be

[LIST=1]
[*][color=#ff0000][i][u][b]This is how it should be[/b][/u][/i][/color][/*]
[/LIST]

This is how it appaers.
