I'm using the Infinite Scroll plug-in with the theme Paragrams from WP Shower, and I selected the selectors based on this topic
Content Selector: #outer > .li_container:first
Posts Selector: .li_container > .mcol, #outer > ul.mcol
Navigation Selector: #nav
Next Page Selector: #nav #navleft a:first
it should work but it needs some kind of hack which beaver6813 graciously made the last time, but it's not compatibile with the new version and the old version doesn't seem to work for me: it gives a "Uncaught SyntaxError: Unexpected token = infinitescroll.init.js.php:111" on the console.
Any assistance would be very welcomed! Thanks in advance!
