Mixed content issue - plusone.js

[gmass69007]

Hello there!

We have a problem on our school website site with prettyphoto module: there is an error with the plusone.js script (allowing to insert the facebook like thumb button), its now obsolete for loading mixed content and google recommends using platform.js instaead.

Can you please check that and make the required update?

Thanks in advance to the team.
Best regards,
Guillaume
