Same issue here. I’ll be watching to see if anyone has input as well.
I don’t have a site of much importance running with this, but I disabled the plugin and things work fine now. It’s on DreamHost’s basic shared plan.
My site uses a Headway Themes theme that I configured. While I’m not doing anything with Headway anymore, the site worked fine and lets my client do what they wanted to do. I wonder if Headway or the theme has anything to do with the garbage being output.
What theme are you using? Custom? Purchased? Part of a framework or stand-alone?
