System Requirements

Minimum and recommended server requirements for AdminLocks.

Minimum Requirements

AdminLocks performs a preflight check on activation and will display a clear error message if any of the following minimum requirements are not met.

Component Minimum Version
WordPress 6.0+
PHP 7.4+
MySQL 5.7+
MariaDB (alternative) 10.3+
PHP 7.4 End of Life

PHP 7.4 reached end-of-life in November 2022. While AdminLocks supports it as a minimum, we strongly recommend upgrading to PHP 8.1 or later for security patches, performance improvements, and full compatibility with future AdminLocks releases.

For the best performance, security, and access to all AdminLocks features, we recommend the following environment:

Component Recommended
WordPress 6.4+
PHP 8.1+
MySQL 8.0+
PHP Memory Limit 256 MB

Running the recommended stack ensures optimal query performance for the audit log, reliable JSON column support for policy storage, and compatibility with the AdminLocks Cloud sync features.

Database Requirements

AdminLocks creates four custom database tables during activation using the WordPress dbDelta() function. Your database user must have the CREATE TABLE privilege for this to succeed.

Table Name Purpose
adminlocks_audit_log Stores all audit log events including user actions, timestamps, IP addresses, and event metadata.
adminlocks_policies Holds policy definitions, rule sets, and role-based permission overrides.
adminlocks_approvals Tracks pending, approved, and rejected approval workflow requests.
adminlocks_snapshots Contains point-in-time snapshots of site configuration for change tracking and rollback.

All tables use the InnoDB storage engine for transaction safety and row-level locking. Table names are prefixed with your WordPress table prefix (e.g., wp_adminlocks_audit_log).

Table Repair

If table creation fails during activation, navigate to AdminLocks → Settings → Debug and click Repair Tables to retry. This runs the same dbDelta() calls and will report any SQL errors.

Browser Support

The AdminLocks settings UI in wp-admin uses a React-based interface. The following browsers are supported:

  • Chrome 90+
  • Firefox 90+
  • Safari 15+
  • Edge 90+

Older browsers may render the settings pages with degraded styling or missing interactive features. The plugin's core functionality (policies, audit logging, menu restrictions) works server-side and is not affected by browser version.

Cloud Requirements

If you plan to connect your site to AdminLocks Cloud for centralized management, the following additional requirements apply:

  • Outbound HTTPS: Your server must be able to make outbound HTTPS requests to cloud.adminlocks.com on port 443. Some restrictive firewalls or hosting environments block outbound connections by default.
  • Valid API Key: You need an active API key generated from your Cloud dashboard at cloud.adminlocks.com.
  • WP-Cron Enabled: AdminLocks uses WP-Cron to send heartbeat pings and batch-sync audit log events to the Cloud every five minutes. If WP-Cron is disabled, configure a real server-side cron job to call wp-cron.php at regular intervals.
Tip

You can verify outbound connectivity by navigating to AdminLocks → Settings → Cloud and clicking Test Connection. The plugin will attempt an HTTPS handshake with the Cloud server and report the result.
