If you've had problems getting pop-up windows on our website to load, you may have a browser setting, toolbar or Firewall that could be suppressing our pop-up windows. We understand the desire to block pop-up advertisements; however WeightWatchers.com uses pop-up windows in important places, such as launching Plan Manager or uploading images in our Community.

If you have a pop-up blocker or firewall on your computer, you may want to consider disabling it while using our website, or learn which settings you can change to allow our pop-up windows to appear successfully.

If you continue to have difficulty after you've followed any of these steps, please contact customer service at techsupport@weightwatchers.com.
