WP Defender Pingbacks - Trabacks fix problem

Hi, wp defender tell me that i have a issue with pinkbacks and trackbacks: "We will turn off trackbacks and pingbacks in your WordPress settings area." If i click on "DISABLE PINGBACKS" botton nothing happen but the strange thing is that on wp backend --> settings --> discussion the option for pingbaks and trackbacks is disabled.

You have access to my site next five days.

Regards

William
