Sorry about that! I made the mistake of updating the actual code but not the installer. See if this update fixes your issue.
As far as the notices go I suppose it is my duty to suppress/handle them better. I will see what I can do however in the mean time, changing your php.ini or adding “error_reporting(E_ERROR | E_WARNING | E_PARSE);” to the PHP file (not the best fix) should suppress the other notices.
