Where is Subscribe settings in admincp ?

[Mean]

My members are automatically be a Subscriber in threads that they comment and open although they do not check the Thread Subscription. Where can I fix this ?

There are various settings, but don't forget sometimes you have to set these default preferences by running a SQL query. Search for 'execute sql query' in the manual.

Ask these members to check UserCP -> Options -> Default Thread Subscription Mode
