SSL Support

I installed SSL on my website, however IFlychat has stopped working, I can see the following errors:

Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at https://api.iflychat.com/chat/610/ssy0lfft/xhr_streaming. (Reason: CORS header ‘Access-Control-Allow-Origin’ missing).(unknown)
Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at https://api.iflychat.com/api/1.1/token/Cuzvy3mGeEle2OgfgWXTB2eL11cQ7p0TY9HCKAuymzMuuLYBrUrSSWVWr21473953158765IKDsnY58qJS721pdtBNwQOBXpaR44vhqBEYy4OMV2OYET3NLe9RsmuHE1/check. (Reason: CORS header ‘Access-Control-Allow-Origin’ missing).

I seems to be asking for the CORS header Access Control Origin to be set, how would I do that?
