Recently updated an install to 4.5.3 and got all file system issues cleaned up and was able to run the scheduled filesynch with no errors, which was very good progress for this install.

However, when I try to create a new folder in file manager, it won't let me: cannot insert nulls into "LastUpdated"

Is the LastUpdated column of the Folders table supposed to allow nulls? I thought I saw some code where it was attempting to update that column to not null, in an error log, and I think I applied it manually as it appeared to have failed during an update. Was this wrong?

Or do I perhaps have an incomplete upgrade where some old code is trying to do the insert to Folders, and not providing a date to LastUpdated?

Thanks -
