Load more comment bug
I have the same issue as reported @ https://wpdiscuz.com/community/bug-reports/load-more-button/
If I click on Load more comments buttons, it extends the comments list with the exact same comments above duplicating them endlessly for every button press.
I do not have the "SG Optimizer plugin" installed, but I do have redis like the other commenters, plus WP Super Cache, as well as Autoptimize and WP-Optimize (Caching disabled) plugins.
I have changed the settings to load all comments for now. This was the page affected.
