Hello I installed the above mediawiki version, and can generate and edit (new) articles. However when I import a backup database from another PC via the command mysql -D wikidb < dump.sql I can display the articles of these database, however when I try to edit an article of these database, or even when I want to generate a new article obtain the following error message Database error A database query syntax error has occurred. This may indicate a bug in the software. The last attempted database query was: (SQL query hidden) from within function "RecentChange::save". MySQL returned error "1054: Unknown column 'rc_old_len' in 'field list' (localhost)". What shall I do (I think I will try out version 1.8 or earlier) but I would like to do, whether this behaviour is caused by some mis configuration of mine. Thanks Uwe Brauer
Your dump is apparently from an earlier version. Run the updaters to update the database.

ok, you are right. When I use version 1.8.4 the same problem occurs but not for 1.7.3 from which I generated the dump. Can you please indicate how to run the updaters?
