After entering my api key, the back end will no longer load.
The error from the apache log is:
[Fri Nov 22 01:28:45 2013] [warn] [client xx.xxx.xxx.xx] mod_fcgid: stderr: PHP Fatal error: Call to undefined function curl_init() in /home/xxxx/public_html/xxxx/libraries/cmandrill/query/query.php on line 134
