WordPress default editor show only Raw mode

Hi there,

we’ve a problem with the editor mode.
The default WP editor only shows “Raw code” while we set to “Single Language Mode”
We tested it with no other active extension.

Please check this screenshot : http://d.pr/i/16PUz

Any help would be much appreciated.

Best regards,
rv.
