Question Aurelia

This is the template  www.joomlart.com/joomla/templates/ja-edenite-ii

unfortunately it's a paid template so I can't get it to test.
it looks like your first picture on a css thing but difficult to see if the website and problem cannot be viewed live
But are you sure it is completely up to date for Joomla 4? sometimes you can update it
ng I see on their documentation somewhere at the bottom. www.joomlart.com/documentation/joomla-templates/ja-edenite-ii
Or maybe ask the  error message that occurredon their forum?

Hi,

Joomlaart said, "That Aurelia template from Kunena uses Bootstrap 5 while JA Edenite II template is quite old and it's built with Bootstrap 3 only so I think there will be conflict in this case. Not sure if Aurelia has option to switch Bootstrap version?"

Strange that they don't have an update for that
but you could try another free template from them eg this one doesn't seem to cause any conflict in my tes
t www.joomlart.com/joomla/templates/ja-campaign
here overview
www.joomlart.com/joomla/templates/tag/free
and with this one www.joomlart.com/joomla/templates/purity-iii
that one is with t3 and supports Bootstrap 3
possible set positions then still the same

Not sure if Aurelia has option to switch Bootstrap version?

This option does not exist. For Kunena 6.x you need a Joomla template that uses bootstrap 5.
