Joomla cache and facebook login

Hi,
I've disabled facebook login in the template, so if I click on the login button in te top right corner it doesn't show "connect with facebook".
But enabling the joomla system cache plugin make the button visible in the login popup... how can I remove that without disabling the cache?

You use both GK cache and GK Ext Cache plugins ? Option to use cache is selected in template developer settings ?

My error, I thought GKCache was to be used in place of Joomla cache plugin.

However, I tried to enable both plugin and the option in template administration, but results are awful: the facebook button is still there and all articles in category blog view are displayed twice, the first time with template style and the second unformatted....

I think I will give up with cache!

Please make sure that you delete old cache or wait until it expires. Of course the default Joomla! cache plugin is disabled ?
