no - I don't have any cache plug ins -- here's what I have running:
AgentPress Listings / Contact Form 7 / Genesis Slider / Google Analytics for WordPress / Google XML Sitemaps / Groups 404 Redirect / Iframe Preserver / Jetpack by WordPress.com / RSS in Page / Social Profiles Widget / Super RSS Reader / WPtouch Mobile Plugin
I believe it was working fine until the update - I hadn't checked it for a few weeks but before that, no problems
