Combination imports did not work for us and the Forum said an upgrade should resolve. The upgrade failed with the following message and now the Admin site is not fully functional and we cannot rollback.
What can we do??
EDIT: The 1-Click Upgrade was used for this and installed the latest MAJOR version with no other choice. It should install the most recent STABLE version,
1.6.1.18
