I recently installed a plugin that was supposed to allow me to easily use a different theme for each category. Unfortuantly, it seems to have messed up my blog but I cannot find where the problem is.
The index shows all of the blog posts three times, and when you go to an individual blog post it is also shown three times. The category pages seem fine though.
I'm not sure if this is allowed, but it is much easier to explain if you just have a brief look at the homepage: http://myfavouritebeer.com.
I have deactivated the plugin, and had a look around, but I have no idea what has caused the problem.
