Missing menu icon

You just need to make the change I gave you in my last post and it will work. Make the font family to "FontAwesome" and do not make any other changes.

Sorry, I should have explained more clearly that I changed to "FontAwesome* in custom.css and it made no difference. Even if I make the change directly using Firefox inspector it makes no difference to the icons. However, if I use Firefox inspector to change to Arial and 2b then the icons display correctly as +. If I change custom.css to Arial and 2b then the icons remain unchanged. This seems to say to me that custom.css is not being read

Just to be clear, I am changing this file:
media/templates/site/ballet/css/custom.css
I am using Joomla 4.4.5, PHP 8.1.22 and HotBallet 4x.zip

Hello,

Yes, but on your website I still see the font family is 'Font Awesome 6 Free'. Please change it to 'FontAwesome'.

Your findings in the inspector about the Arial font are irrelevant here. I am trying to help you to use the Font Awesome and its arrow icon. If you want to use Arial instead of the icon, you can make this change.

Thanks again.
I quoted the case of Arial only as an example of using another font - I do not want to use it.
I have changed custom.css to "FontAwesome" as advised in both sites - live and test site. They are respectively at jadance.co.uk and jadance.co.uk/test_site.

Having made and saved the change to custom.css (see section below), Firefox inspector shows the font to still be Font "Awesome 5 Free". It has not changed despite changing custom.css.

Section of custom.css:
.container_topmenu .parent > a::after {
background: none;
content: '\F078';
font-family: 'FontAwesome';
font-weight: 900;
top: 20%;
}

Hello,

On my computer, the Font Awesome arrows are there now, on both Chrome and Firefox browsers. You might need to clear the browser's cache. Also, your website does not have a proper SSL certificate. If you still don't see the icons in some browsers, this could be the reason.

Thanks for your persistence and help. I cannot get it to work with FontAwesome but I have now got a "+" sign by using Arial 2b - it looks clunky but it is better that "F078".
