The cube icon has gone from the navbar! I have no idea how or why.
Can anyone shed any light on what might have caused this?
It's all users.
This is an on-demand instance with customisations. We have local development and testing instances with are fine. None of the customisations alter the navbar. The on-demand instance kicked me out yesterday (server sync issue or something like that) while working in the module loader. I think this issue started occurring after this.
Resetting user prefs and a rebuild made no difference.
** SOLUTION **
As admin, I unchecked this option, saved, re-checked and saved again. The icon has been restored for all users.
Indeed strange, I never saw this. Is this a vanilla installation or is there some customization in the instance. Just to be sure it is not a cache issue can you reset your user preferences ( 2016-08-29_1556 - SugarCRMSupport's library ) in your user profile and as an Admin run a Quick Repair and Rebuild? Is this happening for one user or for more?
I know this is now resolved but you'll probably find it is that the home module had been hidden, which is represented by the cube.
