Well, I looked at the security log and saw this:
>>>>>>>>>>> 403 GET or HEAD Request Error Logged - April 22, 2014 - 7:14 am <<<<<<<<<<< REMOTE_ADDR: 108.162.222.176 Host Name: 108.162.222.176 SERVER_PROTOCOL: HTTP/1.1 HTTP_CLIENT_IP: HTTP_FORWARDED: HTTP_X_FORWARDED_FOR: ip-deleted HTTP_X_CLUSTER_CLIENT_IP: ip-delected REQUEST_METHOD: GET HTTP_REFERER: http://www.url-obscured.net/wp-admin/admin.php?page=wp-google-maps-menu&action=edit&map_id=1 REQUEST_URI: /wp-content/uploads/wp-google-maps/1markers.xml?u=8657 QUERY_STRING: HTTP_USER_AGENT: Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/34.0.1847.116 Safari/537.36
In other words, the request is coming from the site URL so why is UAEG blocking this request?
