Dear list, maybe a stupid question, but... our wiki lost almost all entries from Recent changes. Mysql logs said DELETE FROM `recentchanges` WHERE rc_timestamp < '20070317115213'; I looked into apache logs, but could not find any http request around the time when this DELETE query was issued. Any possible (automated?) script which deletes recent changes table? Which one? (And why?) The only information I came across was http://meta.wikimedia.org/wiki/Help:Rebuildall.php which states that 1.5rc4 might empty recentchanges table. However we use 1.5.6. Any possibility to rebuild recent changes table from page history data? Thanks for your patience. Regards, Nino
