Thread:Project:Support desk/Fix This Bug:/reply

Hi!

This is a known problem. Currently the best fix available is to add the missing column by hand. This should work using the ALTER TABLE command provided here:

Afterwards you should PURGE the recentchanges table and then run the maintenance script rebuildrecentchanges.php. This should make sure that you do not have corrupt entries in the table.
