Errors after making site https

Hi guys,

I’m just wondering if you can help.

I’m getting a few error messages on my site since going to https

Errors are:
Mixed Content: The page at ‘https://www.retreatmysoul.com/’ was loaded over HTTPS, but requested an insecure script ‘http://static.bufferapp.com/js/button.js’. This request has been blocked; the content must be served over HTTPS.
(index):1 Mixed Content: The page at ‘https://www.retreatmysoul.com/’ was loaded over HTTPS, but requested an insecure script ‘http://www.cntr-di7.com/js/59947.js’. This request has been blocked; the content must be served over HTTPS.

Any ideas?

Thanks,
Adam
