[Plugin: WPtouch] Security Warning message

My site was working fine with Carrington 1.0.2 mobile theme. When I installed wptouch, I now get a security message “Security Warning … There are problems with the security certificate for this site….”. Never got that message with any of the mobile plugins I’ve previously installed. I cleared the cache and disable the plugins that supposedly have problems with wptouch, but no change. Any suggestions? I’ll leave wptouch active for a few hours (until 8pm est 10/30/11) if you want to visit my site to see if you get the same message…

Thanks for any help!

PS: The Surveys 1.01.8 plugin by Binny B A doesn’t format correctly with wptouch.
