We're finally getting around to upgrading an older Joomla and the first step is to change everything to a "modern" template as its a currently running an older Rockettheme GANTRY4 template thats not compatible with latest Joomla.

What are you using on this site, for example? We are testing the Helix Ultimate Template (as Gantry.org was down when we were looking for new Gantry5) but after install it we see the CJforum basic layout seems to be missing things (like the main header with the "Discover dropdown", the 'Start A Topic" link, the "My Stuff" dropdown - this menubar is not populating properly). Rather than spending a lot of time fussing with it, I wanted to know if there is a known Joomla 4/5 template that "just works"... Thanks In Advance!!
