It’s really frustrating. We have many wordpress themes in our care too, and the fact that this can happen without any editing or adding/removing or information or plugins makes wordpress seem very unreliable, for us and our clients.
Bumo (please help no one seems to know what is going on!)
Also clarification of above: the blog and store are functioning (you wouldn’t know from visiting the page that something was wrong with the admin). The admin pages are the only ones that are blank.
** the address bar also does not load the admin addresses either. It goes blank and remains on http://www.joarisgroup.com/wp-login.php .
