Solved Icons and menu items missing after upgrade

I have upgraded to ver 5 on a test server and the forum is now missing icons and menu titles, I have checked configuration and not sure how to fix, can someone please advise where I should look to fix - see screen shot attached.

[UPDATE] To assist others with the same problem
I turned on debug mode (Configuration | General | Enable Debug Mode) and that provided a hint that my menus needed checking, I checked the menu item pointing to the forum and found I needed to update the 'default menu item' setting.
This fixed the missing menu titles, BUT still need help on the missing icons eg icon-folder, icon-clock missing...
I am also still missing the menus when clicking on topic links in the Latest module (even after updating the Kunena Latest module)

go to Kunena - Templates - Crypsis - functions, and activate "CDN Font Awesome '

Thanks Tommy, Yes I have done that and it did help by bringing in some missing icons like the RSS feed icon, but I am still missing icons such as the folder icons and the little icon-clock etc.
And still also missing the menus when clicking on the Latest module links.

Hello intouchweb,

there is a link to your site?

Greeting Tommy

please select the icon type on the "Topic Icons" option located on the "Feature" tab select Bootstrap 2

Thanks 810, when I change the setting to Bootstrap 2 I just lose more icons, like the RSS feed icon.
Tommy I would prefer not to list the site URL in a forum.
