retrieve_conf error 11

I made some changes to my dialplans in the unembedded Freepbx and when I go to apply them I get the following error.

Reload failed because retrieve_conf encountered an error: 11

exit: 11

1 error(s) occured, you should view the notification log on the dashboard or main screen to check for more details.

Does anybody know what this error 11 means? I’m running Elastix 1.5.2-2.3 and FreePBX
