Hi,
I have Caitlin with “Demo Installer” installed both in a web server and locally in my wampserver. I did nothing to any of them after installation. As expected, when reducing the size of the browser the main menu disappears and is replaced by an icon. This is what happens in the live server installation, however, in the localhost installation the icon doesn't show resulting in a non-menu situation. Off course that you cannot check in my localhost but, is this something that you may be aware and may help me?
Now, I have noticed this same issue on a live installation of Grafik that is on the air for some time. The icon doesn’t show up when the main menu is collapsed.
My best regards
wallis

Hi
I have my problem solved. I noticed an error in what I said to you about the installation in my localhost. The truth is that I have installed a third party extension on it and forgot that I did it. Then I suspected that I could have a jQuery conflict and that’s what I had. This extension was loading jQuary by default conflicting with that loaded by Joomla 3.5. When I changed that loading to no, the missed menu icon come to life. The same in that site that I have on the air: also the jQuary in conflict.
Best regards
wallis
