After updating to WP 2.7 similar posts was not working anymore. After a little researching it seemed that YARPP was the perfect replacement.
I tried to active the plugin in on my blog, http://www.tjansson.dk, but even though some related posts was found the plugin also inlcuded the full text and images from the related posts into my original post. I tried to change the excerpt from 10 words to 5 words but it made no difference.
I had to disable the plugin again since it messes up the blog but I would really like to use the plugin. Do you have any idea what is causing the problems? I you wish I could reactivate the plugin for a short while so you could see the effect?
