Ignore the MainCSS page as it does absolutely nothing. It needs to be removed.

hi,
i must delete all additional.css or what?

[Lynne]

additional.css is a template. It has absolutely nothing to do with the Style Manager > Main CSS page. Nothing in vB4 has anything to do with the Main CSS page - it is non-functional in vB4.

so,what should i do for this?
i got this at maincss

You shouldn't do anything except stay away from that page. There is no reason to ever go to that page. That page does nothing for you. It simply hasn't been removed yet from the software.
