When $wgSectionBox = false; there is a horizontal line above the category box which should no longer be there as the box it is used to separate is no longer visible.
According to one of its developer (Mark), Uniwiki extensions for MediaWiki are not under active development anymore "and it is safe to declare them obsolete/wontfix." It is unlikely that there will be any further active development. Closing this report as WONTFIX as part of Bugzilla Housekeeping and adding the whitespace entry "extension[unmaintained]". Please feel free to reopen this bug report in the future if anyone takes the responsibility for active development again.
