Getting an errors

Although some of these issues are not related to Jetpack, the 404 error will be fixed in the next Jetpack release. You can find out more about the issue here:

I wasn’t able to reproduce the errors you faced with Gravatar, though. Do you still see these errors on your end? If so, could you try loading your site in a different browser, and let me know if the error remains?

Thanks!
