Seahub, User Setting, Menu Item Missing [Solved]

Hello, I want to configure Seafile to send E-Mail-Notification on file changes.
But in the Usersetting this Menu Item is missing. How can I fix this?

Thx

You are Seafile Community Edition?

E-mail notifications for file changes is a Pro feature.

Thx, I really was on CE Edition. Now I installed Pro and everything is fine so far.

Good to hear. Can you please mark this topic as solved?
