I read that page before too, but couldn't follow much. But again read that, inserted a column that was missing in page table. Then ran mw-config/index.php from Web, I get this error.
There is currently no text in this page. You can search for this page title in other pages, search the related logs, or edit this page.
When I go to main page, it doesn't show data. Clicking on recent changes, it shows recent changes in pages. However trying to open any of the page, it gives this error:
A database query error has occurred. This may indicate a bug in the software.
SELECT rev_id,rev_page,rev_text_id,rev_timestamp,rev_comment,rev_user_text,rev_user,rev_minor_edit,rev_deleted,rev_len,rev_parent_id,rev_sha1,rev_content_format,rev_content_model,page_namespace,page_title,page_id,page_latest,page_is_redirect,page_len,user_name FROM `jainwikirevision` INNER JOIN `jainwikipage` ON ((page_id = rev_page)) LEFT JOIN `jainwikiuser` ON ((rev_user != 0) AND (user_id = rev_user)) WHERE page_id = '4232' AND rev_id = '8256' LIMIT 1
Error: 1054 Unknown column 'rev_sha1' in 'field list' (jainwikiuser.db.7394013.hostedresource.com)
What should I do to update?
