Anyone experiencing issues with the Cloudflare Wordpress Plugin ?

In their first December plugin update, I can't post. The next day they release another update, but new update still has issue. Now today there is another new version but I don't know if it will cause another problem. Should I disable it first and wait for the stable version?

Try again now after backing up first, there was issues with SSL that affected me. For me it is fixed now only today, and this may have been the issue for you.
