The ep_etherpad-lite plugin is installed by default.

Thank you

Provide steps to replicate.

1- Fresh install using docker-compose.
2 - Addition of plugins using the GUI. Looks like the plugin ep_font_color is faulty

3 - Going to welcome page and trying to create a note results to :

[kimllee]

I have removed the ep_font_color plugin and it looks fine.

[JohnMcLear]

I hope not because its passing tests... https://github.com/ether/ep_font_color/actions

[ChristianGoldapp]

I get the same error just by installing ep_comments_page through the GUI.

The newest version of ep_comments_page in NPM is 11.0.24 and one day old, the version available in etherpad is 10.0.4 from 2025-09-06.

I fixed the outdated information in etherpad and I guess this also affected the installed version...
Now an update to the latest version should be possible
