Since I upgraded to 2.3 my theme is broken :-(
I contacted the designer but after waiting for some weeks I think he has no intention to fix this bug.
I think it's php related. When I click on the a categorie (or tag) it reloads and lists the categorie plus the archive and the first page of the blog below the categorie posts.
What's the fix for this problem?
