The issue disappears when we switch to a different theme. We are currently using the Harmony theme. We have tried updating the theme to the latest version, rolling it back, and even downgrading it. The current version we’re using is "nodebb-theme-harmony": "^2.1.20".<br /> Since the dropdown menu does not open, posts cannot be edited — this affects users as well as admins and moderators. We are using 4.0.0</p>
