I've added the following line to my themes functions.php
I can see in the page source that the file is included:
the path is correct, if I copy the URL and paste it in the browser, I can see the file.
But I dont get the styles in the editor dropdown, they don't show up, I tried different browser, clearing cache,.... I read various posts with people having the same problem, but no fix for it.
I don't use child themes, wp is a new 3.3. install, I have no plugins wich change editor behaviour.
