I wasn't having issues with it either until this update. So I don't think this is an apache issue, it's an app issue and bug that was introduced in this version.
If that's the case, then why would it work for me?
Three people have reported the problem and all three of you are using Apache (which is why I think that it might be apache related).
What version of Apache/PHP are you using, first off?Secondly, do you have some debugging to enable in the php files? I didn't see any in the open.php.
