Bug #8681
Updated by beat over 2 years ago
CB Database check and fix and upgrade tool checks and fixes users table registerDate and lastVisitDate from NULL default to zero-date default (this has no functional but cosmetic effect in the backend).
We never touch Joomla tables, and while this was the case up to 3.10, as the formal specifications matched, in 4.0 the NULL got changed to non-NULL and the default reset to 0000-00-00 00:00:00 as was the case since Joomla 1.0.
This bug and corresponding fix checks specifically for Joomla users table in the checker/fixer/upgrader code.
