style.css issue

Hello,

I have a weird problem with style.css in my theme. I develop with the theme showcase. First of all, i developp in localhost. I transfer the website in my server. Everything is fine… apart style.css.

The file is loaded, when i enter the address of style.css, this is the new file (redesigned). When i open Firebug, this is the original file (old file)… But, when i click on “Source Edit” or “Live Edit”, Firebug is loading the new style.css… ????

And the website uses the old file. I don’t understand. The file is good, the address too… But the website uses old code.

Where is the problem ?

Thanks in Advance.
