Not a really a bug, but I was having issues with maps displaying and then remembered a problem with getting data back from google when connected through a squid proxy.
Add the lines:
//deal with squid proxy
curl_setopt($ch, CURLOPT_PROXY, ‘tcp://your.proxyserver:proxyport’); //substitute the ip or dns name of the squid proxy and the port
above $json_contents = curl_exec($ch); in
/suitecrm/modules/jjwg_Maps/jjwg_Maps.php
I saw a lot of other posts with similar issues and hope this helps.
