How to hide Style name and vbulletin version info?
 

I have the option of "Add Template Name in HTML Comments" unchecked under General Options.

Still my forum homepage shows this:

Code:


/**
* vBulletin 3.8.1 CSS
* Style: 'STYLENAME'; Style ID: 13
*/
@import url("clientscript/vbulletin_css/style-bbba55d3-00013.css");


How to hide the comments now?

And why it does have to mention the version number of vbulletin with style name? Can't the version number be hidden?

And why its written: vbulletin_important.css?v=381

Isn't there a possibility to hide the version number completely? This is a security risk to users who cannot upgrade. I am not in a position to upgrade as of now so want to hide the version number completely.
