Thread:Help talk:Installation/How to migrate to SMWSQLStore3 without shell access?/reply (6)

Finally took the time to check your suggested procedure (thanks for it!).

On my test wiki the procedure worked.

On my "real" wiki it fails - as soon as I uncomment  I get the following error message on all pages:

MediaWiki internal error.

Original exception: exception 'DBQueryError' with message '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 smw_id,smw_sortkey FROM `smw_object_ids` WHERE smw_title = 'Hauptseite' AND smw_namespace = '0' AND smw_iw =  AND smw_subobject =  LIMIT 1 Function: SMWSql3SmwIds::getDatabaseIdAndSort Error: 1146 Table 'usr_xy_9.smw_object_ids' doesn't exist (localhost) ' in /var/www/xy/html/secret_wiki/mediawiki/includes/db/Database.php:918 Stack trace: ... ...

 * 2) 1 /var/www/xy/html/secret_wiki/me...

I tried to run the update script (via webinstaller) but it gives me a white screen after the first step.

On my test wiki there was also an error message (at least on the front page) when I uncommented  (between steps 3 and 4 if you like).

But this error was only shown in the content area and said something like: "MySQL error - couldn't access table smw_objects_id..."

Any help? Thanks!
