Contributions aren't listed if the most recent edit (not the only
edit) made by the user is a minor edit.
It would be great if this bug could be solved by having a configurable
Contributions page, choosing to list minor edits, pages
created, and/or pages edited. But that's a feature request, not bugfix.
So why does
SELECT old_title FROM old WHERE old_user_text=\"$theuser\" AND
old_minor_edit<>\
1
exclude *all* entries which have a minor edit?
Maybe it needs to be
SELECT DISTINCT old_title FROM old WHERE ....
or perhaps
SELECT old_title FROM old WHERE old_user_text="$theuser" GROUP BY old_title
HAVING old_minor_edit<>1
