I have the same problem using the Cookie Notice plugin as the user in the topic here: http://www.dfactory.co/support/topic/cookie-notics-custom-theme/
My site ghostcom.dk uses a custom made theme and the cookie notice does not show up. I tried all settings but no luck. Right now it should appear in the bottom of the page. I use WordPress v3.8.1 (I tried the plugin in 3.8.0 also but with no luck). I have also tried with different browsers – no luck there too.
Any help is appreciated!
