This guide walks through installing DMSI Subscriptions Pro from download to first configuration.

Step 1: Download the Plugin #

Download the dmsi-subscriptions-pro.zip file from your DMSI account or the license delivery email. Do not unzip the file — WordPress handles that during upload.

Step 2: Upload and Activate #

1. Log in to your WordPress admin dashboard.
2. Navigate to Plugins → Add New → Upload Plugin.
3. Click Choose File, select dmsi-subscriptions-pro.zip, then click Install Now.
4. After installation completes, click Activate Plugin.

Step 3: Dependency Check #

On activation, the plugin verifies that WordPress 6.0+, WooCommerce 7.0+, PHP 7.4+, and DMSI DDLS Core 1.0.0+ are all present. If any dependency is missing, the plugin will deactivate itself and display a red admin notice listing the missing components. Resolve all dependency issues before proceeding.

Step 4: License Activation #

After successful activation, navigate to DMSI → License Manager in the WordPress admin sidebar. Enter your DMSI Subscriptions Pro license key and click Activate License. A valid, active license is required for the plugin to function — features are gated behind license validation.

📌 What This Extension Adds: The license activation step is specific to DMSI Subscriptions Pro. Core DDLS has its own license key; each product requires a separate activation.

Step 5: Post-Activation Redirect #

After license activation, the plugin redirects you to DMSI → Subscriptions Pro settings page. This is where you configure all plugin features. See Settings Page Overview for a full tab reference.

Database Tables Created #

On activation, the plugin creates the following tables using dbDelta():

• wp_dmsilm_sp_payment_retries — Payment retry attempt log
• wp_dmsilm_sp_dunning_log — Dunning email send history
• wp_dmsilm_sp_winback_campaigns — Win-back campaign records
• wp_dmsilm_sp_winback_log — Win-back email send log
• wp_dmsilm_sp_pause_log — Pause/resume history
• wp_dmsilm_sp_trial_log — Trial period records
