Alright, I have identified the problem. The 1.82 update/fix was only checking imported users for counting UIDs. The problem with this approach is that some imported users took on the UID of a user who was not imported, but subscribed from a form. Therefore, counting "imported" users would sometimes result in a SINGLE resulting UID instead of two or more. I have fixed the upgrade script to include ALL users, not just imported ones, and have increased the version to v1.83 so that people who previously updated to v1.82 can upgrade again, properly this time. I apologize for the confusion - it should (finally) be over now!
Gail, I have updated you to v1.83 and you no longer have duplicate UIDs. Thank you for checking into the update for me and resolving this issue! This is not something I could have easily re-created on a test installation.
I will be issuing yet another update email to my users... that's 3 in 24 hours :roll:
Regards :wink:
