That was it. I needed to select “Off Canvas” first, thank you!
Nevermind. I fixed it by adding “text-align: left” in CSS for my #slideshow-wrapper element. This needs to be updated in the plugin, though.
Same problem in Firefox but not in Chrome, using jQuery 1.5.1, in case that’s an issue. Were you able to find a solution?
Look up WPBook. You create a facebook app which displays posts that can be commented on via Facebook. It is in PHP so you can’t assign it to a Page but you can put it in the sidebar or in the Boxes page.
