Please navigate to Dashboard > wpDiscuz > Settings > Comment Content and Media admin page and temporarily disable the "The number of words before breaking comment text (Read more)" option. It'll work fine. We'll try to find some workaround asap.
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.
