In another post, you recommend creating a widgetized area to get around the absence of a short code implementation. I’m using a plugin called PageBuilder that lets you create a grid-style center column using regular WP widgets. When I put the tumblr plugin there, it gives the same error as above even though there is only one tumblr being called. I would send you a link, but I can’t get your plugin to “take” — it just throws the error. Here’s the page without it though (I stuck an RSS in for now). Any ideas?
