Doug, apologies there is an error in the code from me retyping it rather than copying and pasting - I was using 2 different computers at the time, one with my Moodle on and one with my emails
In the theme/arialist/frontpage.php code there is a bracket missing from the if statement
if (!isloggedin()) {
$bodyclasses[]='notloggedin';
}
I'm not sure why this would affect the login page though as that uses general.php according to the binarius config.php file - unless it was throwing up the error before getting to the login page itself. I assume as you say the page was blank, you do not have any error reporting enabled - the error in what I copied would then cause a blank page on any page using the frontpage.php layout, so i would assume that is what happened in your case Doug.
Apologies, and the simple bracket added should fix it I've just retested it in Binarius on Moodle2.4 and it worked fine.
Richard
PS. If you need any further help with this, it may be better to repost into the themes forum as the discussion now (if it ever really was) is not really about Security and Privacy.
