Users with $wgPasswordSalt=false before 1.13 will have their wiki destroyed by
upgrade to 1.13 or 1.14, by re-running the web installer. The web installer has
a default LocalSettings.php and so $wgPasswordSalt will not be right in
updaters.inc update_password_format(). My fault, r35923. I probably assumed
that nobody actually used $wgPasswordSalt, but of course it was documented in
various places as a trial-and-error fix for miscellaneous upgrade problems.
Removing update_password_format() is probably the best thing to do, it was
never run on Wikimedia and is unnecessary since b/c code exists. Needs 1.15
release.
Repair of a broken wiki is possible as in the mailing list post:
UPDATE user SET user_password =
CONCAT(':A:', SUBSTRING_INDEX(user_password,':',-1))
WHERE user_password LIKE ':B:%';
Don't try this without backing up your user table first.
