Hello PSX Web Team,
You're welcome, hmm, we're hard to tell you what is the problem causing this issues out without access in your site.
Can you try following this few method?
1.) Re-install the latest version of EasyDiscuss and make sure after re-install is it no hitting any error?
2.) If no hitting any error message when you during the re-installation, try open which Easydiscuss setting page (Yes/No filter buttons) is not save properly the setting > then open the development tools (F12) > click Console > and see got any error show in your console screen (if have show out the error, screenshot for me)
