Could There Be An Incompatibility Between Google Recaptcha and JetPack?

I noticed today that when I click the refresh key on the recaptcha control (‘Get a new challenge’) I do not get the expected new picture to type. Instead I get a scripting error on the console:

Object #<Object> has no method 'getLang_'

After scratching my head I performed the usual troubleshooting exercise of disabling all my plugins (which made the problem go away) and then adding back one by one.

It was JetPack that was found to be the problem. This is odd because I have JetPack running on other websites and Recaptcha is fine. So I continue to troubleshoot …

I’ll let you know when I get to the bottom of this. In the meantime if you find anything do get in touch below.
