I used to use iThemes Security and the Written plugin together with no problems. Written interacts with the site via the XML-RPC interface so they can manage content licenses. I decided to make the switch to Wordfence yesterday as it has better reviews and support and installed the latest version of Wordfence 5.1.5. So far it looks great and I would become a paid member.
I understand the problems which happened before where XML-RPC was disabled and that now supposedly has been resolved. However upon logging into my Written account, I got the message: "It looks like you have attempted to install our WordPress plugin, but we are having trouble connecting to your blog. Do you have XMLRPC enabled on your blog?"
I contacted Written support and they said that Wordfence apparently has disabled XML-RPC. Everything was working before installing Wordfence. How do I check the state of XML-RPC and get it enabled so I can continue using Wordfence?
