Thank you for letting us know and providing the code. Glad to here that the problem is solved. 

Thanks. The problem was indeed with my theme. It has now been resolved by adding the following to my child theme's additional CSS:

.fa{
font:normal normal normal 14px/1 FontAwesome;
font-weight:normal;
}

The problem comes from your current active theme, it loads old Font Awesome version, however wpDiscuz and all wpDiscuz addons using Font Awesome 5 new classes. And if you enable the add-ons the conflict occurs. Please contact your theme support and ask them to update Font Awesome version. 

wpDiscuz 5.31

wpDiscuz Comment Search 1.3.0 

wpDiscuz Widgets 1.3.1

Attached are screenshot without these two addons activated, plus addons with them activated.

2851,2852

Please let us know the versions of the wpDiscuz plugin and wpDiscuz add-ons.

Also please leave some screenshots of this issue. 

When I activate the either "Comment Search" and/or the "Widgets" addon, then Font Awesome icons on my website is suddenly displayed as little squares. The moment I deactivate these addons, the icons are displayed normally.

For clarity, this happens for these addons independently of each other. 

Any advice? I saw this post on the main forum, but the solution is too technical for me. However, if the problem relates to my site only (and not to the addons) then I will get someone to fix it. I just wanna make sure that this is not a bug in the addons.

I'm using a CSSIgniter theme called Pinfinity, using Elementor PRO as page builder - if it is of any relevance.

Thanks in advance for your help!
