You have not set your document root properly. You need to edit /etc/apache2/sites-available/nZEDb.conf or one for nginx, if you use it, to accommodate your folder structure. The way it is set now on your server, it will never work properly.
Yeah, right. And that's why all links work but 4. Did you even read my post? If my config would be wrong, then all links would not work.
It worked before I updated. With the update, "Other" got moved from the left in the menu to the second to the right. Maybe somebody hard coded the path into the code.
Edit: I dug into the code and found the mistake. "{$smarty.const.WWW_TOP}" was missing for these links in www/themes/Alpha/templates/headermenu.tpl
I will report the bug on Github as Wally73 suggested.
