Well, when I code, and I'm calling up a style sheet, I do it this way:
<link href="css.css" rel="stylesheet" type="text/css" />
However, when use Snippetmaster, it inserts something else, and I end up getting this:
<link href="css.css" mce_href="css.css" rel="stylesheet" type="text/css" />
I'm not sure where the mce_href="css.css" is coming from. It has to be coming from Snippetmaster. I take it out, upload the file to the site, then go in and edit, and it reappears.
It happens when I use Snippetmaster Lite; I haven't tried it on the client's site that bought the Pro license yet.
You can see my example here:
