@Jane, I'm not familiar with the plugin enough to say if it's set up correctly or not. I would suggest that you contact that plugin author for their support.
However, in your first screenshot, it appears to me that the domain name should not be there. That box appears to allow you to secure all pages that are sub-pages of a specific URL. I don't think you need that, because you do not (I don't think) have any sub-pages of /registration to be protected. This would be for stores where you have URLs like
In that case, everything beneath "store" needs to be protected with SSL. In that case, this box would contain ONLY /store/ on one line, and all the pages I listed above would be protected. You're not trying to do that. You want to force SSL on the registration page only. In that case, I believe there is a 'secure post' on the WordPress page "Registration" to force SSL for the one page only.
It's possible the error in the second screenshot is related to the configuration. I would remove everything you entered in the URL Filters box, and then just secure the one page by ticking the 'secure post' box for that page. However, I've never used that plugin to know if my understanding is correct.
Please let me know if that helps.
