I've just installed the latest version of b2evolution, the thing is no categories show up, it just shows up as blank, they used to show up, but not anymore, i've made several modifications to the template and to a plugin, but in no way did i move anything related to categories and the strange part is that they used to work perfectly! then istarted to make some posts and they dissapeared, anyonw know why???
