Title: Fixed the two problems

The first issue was solved by adding a define line to the layer that can be used in the widget:

define('QA_ONLINE_USERS_DIR',QA_HTML_THEME_LAYER_URLTOROOT);

The second issue looks like just the fact that you are adding jquery from google while Q2A already has jquery... in my case, anyway, the error disappeared when I commented out the google jquery line, so I've commented that out.
