Been using this plugin successfully on a number of sites & find it incredibly usefull.
However, on current site we are working on it breaks the theme entirely with white screen of death. Details are:
WP: V 3.8 (though same result with previous 3.7)
Theme: http://cyberchimps.com/store/responsivepro/ - latest version, (though same result with previous version)
Widget Logic Plugin: V0.5.7 (though same results with previous version).
All other plugins deactivated.
Note: It does NOT seem to break a Child theme of Responsive - which is strange.
Any idea what might be causing it/where I should start tracing/debugging?
