I just installed the updated version that was released yesterday. However, I still get the same white screen after going to plugins.
[06-Jan-2013 11:45:49 America/New_York] PHP Fatal error: Allowed memory size of 67108864 bytes exhausted (tried to allocate 72 bytes) in /xxx/xxx/public_html/qa-plugin/q2a-badges-master/qa-plugin.php on line 121
Which is this line:
$badges['ancestor'] = array('var'=>365, 'type'=>2);
