The urm_check_user_membership_has_access() function in modules/functions-ur-modules.php was missing the is_super_admin() early-return that the pro version already has. As a result, when content is restricted via a membership rule, administrators were evaluated against the membership subscription check and blocked if they had no active membership — even though admins should always bypass restrictions.

Fix: Added if ( is_super_admin() ) { return true; } at the top of urm_check_user_membership_has_access(), matching the pro version exactly.

How to test the changes in this Pull Request:

1. Install User Registration & Membership. Set a page/post to be restricted to a specific membership plan (restrict → membership rule).
2. Log in as an Administrator user who is not subscribed to that membership plan. Navigate to the restricted page — before this fix the admin would be blocked and see the restriction message.
3. Verify that after this fix the admin can access the restricted content without subscribing to the membership plan.
4. Optionally, connect the admin user to a User Registration & Membership form (as noted in the ticket), then repeat steps 2–3 to confirm the fix holds in that scenario.
5. Confirm that a non-admin user who is not a member of the required plan is still blocked as expected.
