I'm using wp v2.5.1. Ever since upgrading to 2.5.1, when I hit the print link at the bottom of the single post display, what I get on the screen is the blogs header and footer. I no longer get the white page with the post in it.
I was using wp-print 2.3 before I upgraded and it worked fine. Since then, no luck. I've deleted it from hard drive and reinstalled it and it is still broke. Something is broke. Yet I hear that the plugin works for 2.5.1. I also changed themes to the wp default theme and it seems worse. In that trial, the print command didn't even show up at the bottom of the post, or anywhere else.
