I have that bug too, I've checked the source but my pass and username ware correct I hope someone can tell how to fix this... I don't have the time atm to do it.
you can see it here:
Code:
// Set these to your preferences.
// For heaven's sake pick a good password!
$wikiadmin = "user";
$adminpasswd = "pass";
......
......
// From the manual, Chapter 16
if (($PHP_AUTH_USER != $wikiadmin ) ||
($PHP_AUTH_PW != $adminpasswd)) {
Header("WWW-Authenticate: Basic realm=\"PhpWiki\"");
Header("HTTP/1.0 401 Unauthorized");
echo gettext("You entered an invalid login or password.");
exit;
} (not my real login -.- )
