Solved No icons

I think your website and extensions may not be quite the last .
my example is from Joomla! 3.10.4 with the shaper_helixultimate - Default template and Kunena Version: 5.2.8

I just updated Kunena to the last version (5.2.8 / 2022-01-01) and now, no more selection of bootstrap version in the field for the icons types.
Only Font Awesome. But no icons Font Awesome displayed anywhere. Not sure it's a problem for me.
The changelog of Kunena 5.2.8 contains :
Bug fix : Fixed icons disappearing in Kunena 5.2.7 (#8634)

My Joomla is also 3.10.4.

ok but in joomla do you really use this shaper_helixultimate - Default Template ?
and is the website online to view it?

okay can you join the kunena category as a test Category Icon: eg enter fas fa-atom and see if that works
got that from here when you click on start using this icon the correct code comes up
sample icoon code


 

ok i will come back to my attempts with Helix Ulimate template indeed does not allow all edit icons in the editor .
If I install a lempate eg Phoca POS as a test and set it up a bit, I can see the icons.
so i think it would be wiser to look for another template

Last minute : Now it works, with Helix Ultimate and my Joomshaper template.
After my last update of Kunena, I entered a wrong Font Awesome code.

Problem solved. Thanks for your help.
