Thread:Project:Support desk/No login page after 1.21.3 to 1.22 upgrade - Uncommitted DB writes?/reply (20)

These lines are added to LocalSettings.php: $wgShowSQLErrors = true; $wgDebugDumpSql = true; $wgShowDBErrorBacktrace = true; But all I get is:
 * Notice: Uncommitted DB writes (transaction from DatabaseBase::query (LCStore_DB::get)). in /home/[...]/html/includes/db/Database.php on line 3944

Where do I check for more hints or where's some error-log for the notice?

Setting $wgJobRunRate to 0 or 0.01 did not change anything.

This bug keeps me from using my MW at all.
