Hello.

It seems the upgrade procedure did not go completely well. Did you encounter any problem during upgrade procedure? Did you upgrade manually, or using Kentico Installation Manager tool? When you navigate to Site Manager / Administration / Event log, is there any record related to result of upgrade procedure saying "Upgrade successful" or so?

PM stands for Project management, which is one of new features in KCMS 6.0, so I would recommend you to upgrade once again and make sure to follow all upgrade steps according to instructions. Please note down any particular issue or error message you receive during this upgrading. Thank you.

Best Regards,
