MemberPress: Restrict Signups for Northern Ireland-Based Users

This code snippet will restrict signups for Northern Ireland-based users on MemberPress registration pages. Additionally, it ensures that the country field is mandatory during signup.

To update the error message displayed when a user from the restricted country tries to register, adjust the Sorry, signups are not allowed from Northern Ireland. error text on these lines:

$errors[] = 'Sorry, signups are not allowed from Northern Ireland.';

To update the error message displayed when a user tries to register without selecting a country, adjust the "Country selection is required to proceed." error text on this line:

$errors[] = 'Country selection is required to proceed.';
