Question How to select the icons available in the editor ?

The templates crypsis and crypsisb3 gives very bad displays, and error messages with debug on.
But the menu CKeditor or BBcode are back, only when I change the Joomla configuration on "Debug mode" !
I have no idea why.
And, anyway :

• The main problem is still there : The icons of CKeditor work but are all displayed.
• Even on BBcode, on which I can select the icons to display, most of the icons don't work.

can you check if your template is Templates: Customize
here you have this file " file "/js/bootstrap.bundle.min.js" in template"
which causes most icons not to work. that's why I give it a different name in helix ultimate.
but why the icons can't be turned off separately in the Template : crypsisb4 tab Bccode could also be related to that
And I already have that with several kunena users using helix based template seen by renaming it suddenly started working

OK. CKeditor is back with the file bootstrap.bundle.min.js renamed.

But : "can you check if your template is Templates: Customize" : where do we find this parameter ?
For now, I have still ALL the icons of CKeditor. I can't display only the icons selected.
With BBcode, I can select the icons, but they don't work properly : F5 necessary to quit the forms (full width), to add a link or an image.

Sorry the translation of my answer apparently did not go well.
I meant at the Administrator > extensions > Templates: Styles Templates: Customize (your website template).
but why the editor select doesn't work 100% for you
seems a bit in this case you would see if you can find something similar in your template .
something similar
so it could also be in the js folder of the template in the bootstrap.min.css

The only configuration that looks and seems to work fine is Crypsisb4 with CKeditor.
But is the buttons selection supposed to work with the tab BBcode, and CKeditor selected ?
If yes : it doesn't work for me.
If no : I have no idea how to make it working.

can't think of any more tips on where to look.
I don't have this (paid) template, so unfortunately I can't search for the problem locally and test it.

Crypsisb4 is a free template.

yes I know
I think that's where the misunderstanding arises.
So it is that the kunena Template has a conflict with you purchased Joomla template Joomla 3.10.8 template Folium (Helix Ultimate).
And I don't have it(template Folium) so I can't test where it is exactly

OK. I have misunderstood.
I will contact Joomshaper.

Thanks for your help.
