After upgrading from MW 1.20.8 (PHP 5.3.3 and SQL 5.1.66) to 1.21.3 I get the following PHP notice for every special page to be updated:
PHP Notice: UpdateSpecialPages::execute: No transaction to commit, something got out of sync! [Called from DatabaseBase::commit in /.../includes/db/Database.php at line 3068] in /.../includes/debug/Debug.php on line 283
$wgDevelopmentWarnings was set to true before and after the upgrade.
The special pages however are being updated.
I will also be nice to know how to get this in sync.
Version: 1.21.x
Severity: normal
