This extension comes with MediaWiki and only required re-enabling in LocalSettings. I restored the old extensions in forms compatible with MediaWiki 1.26. #17 /home/unitygal/public_html/wiki/index. I then modified the LocalSettings.php file as advised. #16 /home/unitygal/public_html/wiki/includes/Wiki.php(467): MediaWiki->main() #15 /home/unitygal/public_html/wiki/includes/Wiki.php(602): MediaWiki->performRequest() #14 /home/unitygal/public_html/wiki/includes/Wiki.php(312): MediaWiki->performAction(Article, Title) #13 /home/unitygal/public_html/wiki/includes/Wiki.php(448): ViewAction->show() #12 /home/unitygal/public_html/wiki/includes/actions/ViewAction.php(44): Article->view() #11 /home/unitygal/public_html/wiki/includes/Article.php(555): OutputPage->setPageTitle(string) #10 /home/unitygal/public_html/wiki/includes/OutputPage.php(894): OutputPage->setHTMLTitle(Message)
