Disclaimer: I have no idea how this is used in vanilla... but I'll try to
answer it anyway :)

The easy thing is to look into your apache log file called error.log
somewhere in your apache directory. (normally apache/logs) - There should be
a 404 error message for this stylesheet file name... - if not... something's
wrong with your HTML or I don't understand how stylesheets work...

If you found your 404 error you can see the path in which it should be
contained... if it is /cgi-bin/vanilla_jason.css - forget it. -> change the
href to "/vanilla_jason.css" or something similiar and move your stylesheet
into the apache/htdocs directory. - in the vanillasbx this is called
apache/static (who cares abut filename conventions....)

hope it helps.
