Packs & Imports Disabled?

Packs Feature Disabled

We are currently using the Google Calendar pack to sync employee accounts and have one universal calendar in the company. So far there are 6 accounts synced but now the packs & imports feature has become disabled and we can no longer update or amend the calendar. The page is not locked but that is the reason given for features disabled.

Has anyone else encountered a similar issue?

Thanks in advance!
