I’m getting this too, and it’s preventing the plugin from working. Interestingly, I was able to configure the callback URL, but after that, I get the blank settings page and it doesn’t appear to be posting to my buffer.
I’m running WP 3.4 and 0.8 of the plugin. I’m on PHP 5.3 (I can’t tell any more finely-grained than that from the tools my host gives me). The blog is self-hosted at https://bretwortman.com/ and is pretty new so it might well be my error that has caused this. If there’s anything else I can check and let you know about, just say the word.
Thanks!
