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.
