- until now, Portal was not loaded if members were disabled. With the
introduction of Tips & Donations, signed-off readers can also make
payments, using the Portal link /#/portal/support.
- now, Portal is loaded when Tips & Donations are enabled, even if
Memberships are disabled
- depending on the member signup access, the top bar / trigger button
Portal buttons are hidden as before (signup/subscribe hidden if access is set to none, subscribe hidden if
access is set to invite-only)
- for any other signup / signin Portal links (e.g., added by the theme,
or added via a Post/Page), a new popup informs the reader when
Memberships are disabled: "Memberships unavailable, contact the site
owner for access".
