Installation

Replacing Restrict Content Pro (RCP) with SMM:

1. Deactivate Restrict Content Pro (RCP): Go to the Plugins page in WordPress and deactivate RCP.

   [!WARNING] Do not keep both RCP and SMM active at the same time to avoid PHP class redeclaration conflicts.

2. Upload SMM: Upload the simple-membership-manager folder to the /wp-content/plugins/ directory.
3. Activate SMM: Activate Simple Membership Manager through the Plugins menu.
4. Data Verification: Go to Restrict → Memberships. SMM will automatically detect and reuse your existing RCP database tables, seamlessly picking up all your customers, subscription levels, active/expired/cancelled memberships, and notes without any data loss.

FAQ

Does SMM support payment processing?

No, Simple Membership Manager is a lightweight drop-in replacement focused on membership management, content restriction, and user role synchronization. It does not contain any payment gateways or payment processing logic.

Can I customize the restricted content message?

Yes, you can use the rcp_restricted_message_filter filter to customize the message shown to non-members:

add_filter( 'rcp_restricted_message_filter', function( $message ) {
    return '<p>Custom warning message here.</p>';
} );

Is SMM compatible with menu visibility controls?

Yes, SMM implements the exact function compatibility stubs used by the advanced-menu-items-visibility-control plugin to hide or show menu items based on membership levels.

Changelog

1.0.7 - 2026-08-28

• Fixed: The "View details" link on the Plugins page displayed "Plugin not found." when another plugin's plugins_api filter discarded the modal payload. The updater now rebuilds the plugin information object on the plugins_api_result filter (with a safe fallback payload) so the details modal always renders.
• Improved: The updater resolves the plugin file and folder dynamically from SMM_PLUGIN_FILE, so updates, folder renaming, and the details modal keep working even if the plugin directory has been renamed.

1.0.6 - 2026-08-26

• Improved: Activation emails (paid, free, and trial) now name the membership level instead of the site in their subject line, e.g. Your "Level name" access on Site name has been activated.
• Improved: Activation emails use a dedicated ACCESS ACTIVATED header instead of the generic greeting. Other notification emails keep the greeting from the email header setting.
• Improved: Activation email body wording aligned with the new subject: Your "Level name" access has been activated.
• Fixed: The email footer sentence ("You are receiving this email as a member of…") was hardcoded in English and is now translatable.
• Translations: Four new strings added to rcp.pot and translated in rcp-fr_FR.po / .mo.

1.0.5 - 2026-07-06

• New: Membership level filter dropdown on the Memberships admin page to filter the list by subscription level. The filter combines with the status views and search, and is preserved when switching between status views.

1.0.4 - 2026-06-26

• Removed: The "Members of any paid membership level(s)" option from the subscription restriction metabox (rcp_subscription_level_any_paid).
• Removed: All index.php files.

1.0.3 - 2026-06-25

• Improved: Upgraded default email layout to a modern, responsive, card-based HTML template with clean header, body, and footer sections.

1.0.2 - 2026-06-25

• New: Real-time autocomplete user email search when adding a membership manually.
• New: Client-side validation and styling on the add membership form to prevent crashes.
• New: Graceful server-side validation error redirects to avoid blank error pages.
• Removed: Price and Signup Fee options on membership levels page as payments are not processed.

1.0.1 - 2026-06-25

• Initial release
• Drop-in compatibility for Restrict Content Pro database tables
• Standard user management, level CRUD, and customer overview pages
• Integration of GitHub auto-updates and bug reporting utility
