Users cant comment anymore. Admin cant either

Hi guys,

I dont know what i did, but commenting on entries doesnt work anymore.
i changed some settings, but not for commenting.

In admin, commenting is on, but new news doent ave de commentform. Permissions are good, as far i can see.
also when i edit an old news item, commentform gone.

I feel its a little thing, but it is so little, that i cant find.
Someone can help me with this?

I found it.
For some reason, i untick the Feedback option.

Silly, but true
