Hello,
I just installed this add on for my website which is currently 1.3.9h I have followed all direction however on your statement "Now click "Facebook Integration" on the left. Towards the bottom you should see "Installable to?". Uncheck "Users" and add a check next to "Facebook Pages" instead."

there is nothing on Facebook Intergration that has that option. when i go to the app part to add app it sends me to my website. also the http://apps.facebook.com/---------/ is blank where the -------- lines are.

How do i know if it is working properly without your directions not being on the facebook app section?

Thanks
