Comments tab in file details is not present

After an upgrade to version 10.0.8 from 9.1.3 it seems all well except for the comments tab in file details side bar which is not present.

In previous versions I used the comments app which is not supported anymore.

Any suggestion is welcome.

Maybe you don’t have enabled the comments app providing this functionality?

Ok, I solved the problem.

During the upgrade I had to delete a previous version of comments app not supported anymore.

To make it appear again I had to copy the folder comments from the new version of owncloud.
