[Plugin: Jetpack by WordPress.com] Can't comment

The trouble I’ve been having (and thanks to thebluegger for pointing to this thread) is that the comment form does not appear at all. However, this is not consistent behavior: some people are able to comment just fine, others not so much. I’ve tested on Mac in FF Safari and Chrome, all zippo. But I just went back again, and all three browsers are working.

My client offers similar anecdotes. She regularly gets contacts from people who say they’re not able to comment on posts where there are already a bunch of comments.

I’m guessing this probably has something to do with the third-party forms issue that also screws up Bad Behavior as well, though I’ve deactivated that plugin:

Finally, I have to say that automatically turning features of Jetpack on is a bit of a crap move. But that’s a comment for another thread, I suppose.

Seems like so RebelStar, the error message is “Refused to display document because display forbidden by X-Frame-Options”, jetpack comment display the comment using iframe which loads most things directly from WP’s servers, and that error message usually appears if the iframe source URL forbids the access, so it should be an issue from the servers.

Yeah, glad it’s fixed quickly 🙂

I might submit that, since it wasn’t working for me a few hours ago, I’ve done nothing since, and now its working, you may be chasing a red herring. Just a warning/suggestion.
