I'm experiencing the same problem with etherpad-lite version 2.2.4.

I'm experiencing the same problem with etherpad-lite version 2.2.4.

I released a new version of ep_comments_page. Could you please try again?

[brknkfr]

ep_comments_page version 1.0.37 seems to work now.

@SamTV12345 I can also confirm this fixed the issue. Just for reference as other plugins might need the same fix, the commit was a8b5a77 ?

Yes. The io variable was globally scoped but caused issues when I combined everything into a JavaScript file. So if you find another plugin that needs this patch please open up a pr and @ me
