Problems with authentication (I think)

Hello all, What I have: Windows webserver running PHP 4.34 and MySQL 4.0.17. The knowns: Doing the PHP test works and I get back all sorts of information, and PHPBB2 works as advertised with no problems, so does PHPMyAdmin. My Problem: I've tried a number of PHP scripts to do various things (some just to play around and learn, and some because I really want them on my web server.) The three problems I usually encounter with the problematic PHP scripts are: 1. When I hit the page, it just returns a blank page. This happens with: PHPTest http://www.resynthesize.com/code/phptest_info.php Proxy http://sourceforge.net/projects/sbp/ 2. When I hit the page, it needs some authentication for login, and even though it appears to take the login, nothing really happens (i.e. it didn't log me in, so I can't go anywhere. This happens with: Scubaman Dive Log http://www.ivains.com/scubaman Directory Indexer http://autoindex.sourceforge.net (only when I enable the authentication for user logon, otherwise it works fine) 3. Parts of the PHP script work, but others don't. This happens with: GoRedirector http://www.studentplatinum.com/scripts/ (It will return the values from MySQL that are in there, but I can't delete, add, or administer it in any way, nor does the actual PHP redirector itself work.) I don't know enough about PHP yet to really know where to start looking. Any help would be greatly appreciated. I thought it had something to do with Global Variables being disabled in the php.ini file, but I re-enabled that to test it, but it didn't help.
