I tried posting this through support on my WPAdmin W3TC page - but kept getting submit errors.
After deactivating all plugins, then reactivating them one by one did indicate that W3TC activation breaks the twitter feed display in my site footer. See bottom of http://jeffreifman.com
Following Elliott's instructions at bottom of this feed

I tried turning off js minify and emptying cache - but no luck.
Any way to activate W3TC and have the theme twitter feed successfully display?
