I realised that the Navigation menu has disappeared when displaying a visualforce page in Salesforce1 for communities
I have created a very simple page with no logic at all to verify this which is the following
<apex:page showHeader="true" sidebar="true">
Hi {!$User.FirstName}
</apex:page>
When I login as a normal user the page and the navigation menu are rendered as expected.
When I login as a community user (Chrome using /one/one.app and Safari in iOS) the navigation menu is replaced with the back button !
It was working fine until the org was upgraded to Summer 14.
Has anybody else experienced something similar ? Is this normal ?
