Just noticed after years of using smart archives, my archive page was broken - complete blank screen. Narrowed down the problems to other plugins.
1. sharebar - when the plugin is activated - 'fancy' no longer works (even if i disable the use of sharebar specifically on my achives page) - it ends up listing everything instead.
2. my main issue is that it goes to a complete blank page when using wordpress 'jetpack' which is becoming increasingly standard on wordpress installs.
any work arounds?
