Liferay 6.2: Documents and Media portlet subscription feature not working for standard user

Question

I am using Liferay 6.2 and want to set the options for the folder subscription feature in the Documents and Media portlet. My problem is that the button "subscribe" only appears for my Admin-user. For every other user of my portal it is not showing up.

I checked every permission that is set for users in the portal and the subscription-feature is nowhere to be seen. How can I have my normal users subscribe to folders?

Where can I find the right settings?

TIA

Answer 1

I found the solution myself.

The problem was that the users were not assigned to the open site. Although they had all the roles they needed they HAD to be assigned to the site, not only the community.
