How do I stop the italic quote style?

[prettyboi]

Okay, for some reason everytime I quoted a message and all my quote messages on board are in italic styles like this here EXAMPLE HERE OF THE QUOTE STYLE and it's an automatic thing.

Soemone mind checking out my page and please explain to me on how to stop this? My url site address is: http://www.asianunityforum.com
