Where is the styles.css file?
 

Can somebody point me to the location of the css file that sets the styles for vbulletin, please?

I've used my own style sheet for our header and must have used the same name as one of the vbulletin style ids. I just need to have a quick look at the vbulletin style sheet so that I can determine which of my style ids I need to rename.

thx :)
