Solved Awesome Font change to blinking question-excalamtive mark

Hello !
Not sure whether I am in the right category to post. Anyway, here's the problem I am facing.
I am on the latest joomla version, my template is Gantry Helium (latest version too) and I have the latest Kunena forum version (5.2.3). My template makes use of the Awesome Font library. I recently updated Gantry and Kunena about the same time.
Some menu item icons have been since replaced by blinking icons (question mark then exclamative mark). And this only happens when I am on the Kunena page.
Here 's the link to the issue : www.4u2learn.fr/joomla/forumkunena
I contacted Joomla support and got a suggestion that Gantry might be responsible but they also noticed that the issue only appears on the Kunena Forum link.
That's why I'm turning to you. If someone could have a look and keep me updated on this, that would be great because I really have no clue about what causes the issue.
Thanks in advance !

Hello,

I have looked at your site, the menu item "Contact me" has a blinking fontwaesome icon. It seems that the code for this icon is incorrect, in your source code i can see that :

If you look on fontawesome site the code for this icon is different

Yes, thanks, that's exactly what I noticed but why does it only happen on the KunenaForum menu link ?
I have Gantry Helium installed (as a theme) and updated. Gantry lets you choose your own icons in their parameters thanks to an icon picker. There's no way to use custom code in their parameters, so to replace with a "fas fa-envelope-open" icon.

Any idea ?

The code fa-envelope-open-o is coming from fontawesome 4.x

In Kunena 5.2.x the compatibility layer with fontawesome has been removed, maybe i need to add it with a setting to be loaded only for users which needed it

In file /libraries/kunena/template/template.php you can that code to line 1974 to add the compatibility layer with fontawesome, so change that :

to that :

Hi !
No need to insert code. I found a better way to disable the Awesomefont icon library. In the crypsis template parameters, there is a way to turn off this library :

Thanks anyway. Now, why does it conflict with Gantry ? I don't really know, but the issue is solved !
Thanks again !

Gantry use fontawesome in version 4 so it's the reason

that's it !
