How do I roll back this upgrade?
Just like any module install, a rollback isn't possible without a full site restore.
Am I the only person who has paging issues?
We haven't had any other reports on this issue.
Also, I am being told I can renew my support for a year but this feels a little strange in light of who owns Active Modules now. If I pay for support who will actually support me? the DNN forums?
It's no different than the support you had before. If you renew, you have access to the help desk again and we can provide hands on support.
