I have changed 3 .php-files of the core XF-code in order to make my Forum a "Private Community". RecentActivity.php FindNew.php Members.php according to this: http://xenforo.com/community/threads/how-to-hide-the-whats-new-tab-from-visitors.26434/#post-318434 Question: What happens to those 3 .php-Files when I upgrade to the latest XF-version ? I am still running XF-version 1.1.1 I am just wondering if those 3 Files will be updated automatically to the new XF-version when I upgrade the software ? How should I handle this properly ? Appreciate your advise!
