Thread:Project:Support desk/Database error after updating to 1.20.4/reply (6)

Oh, you are right. The column is still present in the tables.sql file in MediaWiki 1.20. Sorry.

Maybe you can restore the old contents from that column. If you have a backup of your wiki, where the column is still there, you could copy the contents into that column again. Or, if you have not done too many changes, you could replace your DB with a backup, in which the column is still there. However, as I understand the note in tables.sql, this column has not been used in newer releases anyway.

But I would make sure, that all other columns are there as needed. So what I would check now is, if any other columns are missing in your DB.
