css Internal Server Error. Help!

hi at all!
i've installed accordeon ck and all is working well.

unfortunatelly i can't load css and in firebug i have:

Failed to load resource: the server responded with a status of 500 (Internal Server Error) http://www.@@@@@@.com/modules/mod_accordeonck/themes/default/mod_accordeonck_css.php?cssid=accordeonck120

Someone could help me?

Thanks.

Hi
this can be due to a high level secutiry rule that blocks the PHP file.
Check on your server, the htaccess, or anything that can block it
Also check that the file exists in the folder
