Issue: Icons not visible in ThemeHouse UI.X 2.2.0

This is Not a Bug. It is caused by ThemeHouse disabling FontAwesome, which is a default component of XenForo, in some of their styles.

This was reported here:
https://www.vaultwiki.org/issues/6126/
and here:
https://www.vaultwiki.org/issues/6099/

According to their documentation (https://www.themehouse.com/help/docu...x2/uix_icons):
Is this something you can work with (and which can be done on your side), or is this something we have to do?

If the FontAwesome icons were still loaded in, then they would be visible on your site. I believe their claim is referring to the fact that Font-Awesome-based CSS class names were mapped to MaterialDesigns icons, which is not the same as still loading the Font Awesome 5 Pro font into memory.

VaultWiki cannot use a font other than FontAwesome. MaterialDesigns is not a 1:1 replacement of all the icons within the font.

In default XenForo, a number of @font-face rules in a template called "fa.css" sets up the font named "Font Awesome 5 Pro" among others. The default XenForo template called "helper_js_global" loads it on line 2. Since that font is a core part of XenForo, VaultWiki expects it to be defined already.

My understanding based on other reports is that some ThemeHouse styles modified this in some way. Since it is a third-party custom style (not made by XenForo themselves) and has removed a core part of XenForo, it is your responsibility to make sure the missing core font is still loaded.

I've had a support ticket with theme House completed in the past.
