Members App Registration Form Failing
I'm trying to set up a basic members area for a website. I've installed the app and have a Members area in the Perch admin. I've copied the basic registration form from the docs and then added it to the page which will act as the sign up, however when I enter some details in the form to test it, the registration isn't working. The form is not registering in the members area of the admin interface, and no member is listed under members. When I've filled in the form and clicked the register button, the page refreshes but nothing seems to happen, it loads the page as if the form has never been submitted and no errors or anything shows in debug.
How can I work out why this is failing?
Edit: I should add, this is all on my local copy running under MAMP with php 7.2.8.
