Plugin Compatibility Checker

The Plugin Compatibility Checker helps you keep your WordPress site stable and secure by scanning installed plugins for PHP, Database, and WordPress version compatibility.

🆕 WordPress 7.0 Database Readiness WordPress 7.0 introduces stricter database requirements (MySQL 8.0+ / MariaDB 10.6+). Many hosting environments still run older database versions which may silently block updates. This plugin now detects database compatibility and warns you before upgrading.

$1/month License Required (Entry Plan) You must subscribe to the CompatShield Portal ($1/month recurring) to obtain a license key. Once activated, you will be able to see plugin compatibility results (up to PHP 8.5) and database compatibility directly inside your WordPress admin.

Pro Version (Upgrade) Upgrading to Pro unlocks the full CompatShield Portal Dashboard with advanced features — vulnerability summary, detailed scan results, notifications, historic analysis, plugin issues overview, premium ZIP upload scanning, and multi-layer compatibility intelligence including database upgrade readiness.
