First I wish to say that I'm enjoying very much using your widget. I intent to purchase the premium version when the site is a bit more developed.
I upgraded recently to 2.0.4 and am now encountering a very strange problem - when I use the 'post in category' rule to try and show an image in the header of blog posts with a certain category name, the image also appears under the header on the homepage. This only started with the upgrade. It worked perfectly before.
Here is a link to a post where the image appears just right: http://bit.ly/12GXlvp
and here is the link to the homepage where the same image should not appear: http://bit.ly/VWuY6x
BTW - the 'Category' rule doesn't seem to work at all.
