I am trying to get shared uploads working. I want my Commons-equivalent to be the Xinki Wiki at xinki.org.uk/wiki/ and (at first, for simplicity) another wiki at garykirk.org.uk to be able to use those files. In garykirk.org.uk (Wiki B)'s LocalSettings.php I have:

## interwiki $wgUploadNavigationUrl = "http://www.xinki.org.uk/wiki/Special:Upload";

$wgUseSharedUploads = true; $wgSharedUploadPath = 'http://www.xinki.org.uk/wiki/images'; $wgSharedUploadDirectory = '/home/gkirk/public_html/wiki/images/'; -- this is what I get when there's an error ie call to an extension not installed; I assume it is correct. $wgHashedSharedUploadDirectory = true; $wgFetchCommonsDescriptions = true; $wgSharedUploadDBname = 'gkirk_xinkiwiki'; # xinki wiki $wgSharedUploadDBprefix = 'mw'; # Table name prefix for media files wiki - mw is the prefix the Xinki Wiki (Wiki A - Commons - uses) $wgRepositoryBaseUrl = "http://www.xinki.org.uk/wiki/Image:"; Now when I try to add an image to a page, even an image which does not exist - [[Image:Imadeupthisimagename.png|Made up]] - I get: Database errorA 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 "ForeignDBFile::loadFromDB". MySQL returned error "1054: Unknown column 'img_sha1' in 'field list' (localhost)".

Wiki B is running MediaWiki 1.11.0; Wiki A is running 1.10.0.

Any ideas on what's wrong?

Regars,
