The page has a JavaScript Google maps app. It was part of the CMS, not the forum, but users could log in to retrieve saved maps. The page is here (vB4)
http://www.roadtripamerica.com/maps/mapwizard.php but in vB5 the page crashes on the PHP line "require_once('./global.php');" because there is no global.php in the appropriate directory (or anywhere else).
That PHP code is commented "Require back end", I assume because logging in is not usually part of the non-forum pages. Is there anything I need to do to be sure that users can log in (and the code can test for vBulletin variables) in the non-forum pages?
