I got the journals working by replacing the reference to $PHP_SELF in the form action line in the journal functions.inc file to:
Text Formatted Code
"<form action="" . $_CONF["site_url"] . "journal/index.php" . "" method="post">";
I changed 3 form references in all.
$PHP_SELF seems to be working ok in the href tags, just not with the Form Submit? Can anyone tell me why this might be?
