Hi, I also have a problem with missing parts. I changed the template and turned off all plugins. The problem remained. I attach a screenshot and a link to the site.
Please navigate to Dashboard > wpDiscuz > Settings > Styles & Colors admin page, enable the "Load Font Awesome CSS Lib" option, then delete all caches and check again.
In case you want to say thank you! 🙂 We'd really appreciate if you leave a good review on the plugin page. This is the best way to say thank you to this project and the support team.
