Your IP address does not match this session. Help  - I am on the plan that does not involve email support. I just want to change the setting to allow me to only have subscribers post or respond. 

As you're utilizing CloudFlare, you will need to enable "Trust IP addresses provided by proxies?" in ACP -> System -> Advanced Configuration. Otherwise, your IP address will change each time CloudFlare swaps you to a different server as it won't use your device's IP address. You also can run into issues with users and IP addresses if you do not do this.

Just a note, you found support (Hi!). The method which you go to obtain support has changed but the level of support has not 🙂 .
