Hi, I am trying to use IMAP Authentication on the wiki, but just can't get it to work. I've spend quite some time on it, and am using the latest 1.3.7 install. I've ensured I have all the code correct, as taken from this site reference:
http://phpwiki.sourceforge.net/phpwiki/UserAuthentication

I have included the following definitions in index.php:
define('ALLOW_BOGO_LOGIN', false);
define('ALLOW_IMAP_LOGIN', true);
define('ALLOW_USER_LOGIN', true);
define('REQUIRE_SIGNIN_BEFORE_EDIT', true);

and have of course ensured my IMAP_AUTH_HOST is set. I am using our incoming pop3 server, which I assume is OK.

But the problem I am still having is that whenever a user with (or without) an account on that server tries to login, they are displayed a blank page. Completely blank. The url is:
http://localhost/wiki/index.php?pagename=HomePage&action=edit

but the page is very very white!!!

Any input would be highly appreciated.

Thanks very much.
