Thread:Project:Support desk/help to restore an abandoned wiki/reply (6)

Do you really have overwritten all files? Can you try it again? Maybe you can try to delete all files (make sure you really have a backup ;)) and copy all MediaWiki 1.23 files to the location of old MW and run the update script (copy the LocalSettings.php from old MW to new MW installation). Be sure: If there was some extensions installed, please comment out the lines in LocalSettings.php (require_once).
