Thread:Project:Support desk/Database error after upgrading

Hello,

I just installed the latest version of mediaWiki (was obligated to do so after our previous server running it crashed) I tried to restore our DB backup and now it gives me the following error:

A database error has occurred. Did you forget to run maintenance/update.php after upgrading? See: https://www.mediawiki.org/wiki/Manual:Upgrading#Run_the_update_script Query: SELECT page_id,page_len,page_is_redirect,page_latest,page_content_model FROM `page` WHERE page_namespace = '0' AND page_title = 'Hoofdpagina' LIMIT 1 Function: LinkCache::addLinkObj Error: 1054 Unknown column 'page_content_model' in 'field list' (localhost)

I have absolutely no idea what version was running previously. Is there any possibility of restoring our data? I already ran the update.php script. it does make media wiki work but empties the database as result.

Kind regards
