Plugin Compatibility Checker reviews installed plugins for PHP, database, and WordPress version compatibility. With an activated license, Entry Plan shows PHP compatibility results up to PHP 8.5 and basic database version detection in WordPress admin.

What Entry Plan shows

• PHP compatibility results for installed add-ons, up to PHP 8.5.
• Basic detection of the site's MySQL or MariaDB version in WordPress admin.
• Rescanning after plugins are installed or updated, so they can be included in the check.
• A “No Data” result when compatibility information is unavailable. This can happen with some custom or premium plugins, or versions removed from the public plugin directory.

Entry Plan requires a recurring $2/month subscription through the CompatShield Portal and an activated license key. Without license activation, visibility of compatibility results is limited.

Database checks for WordPress 7.0

WordPress 7.0 has stricter database requirements: MySQL 8.0+ or MariaDB 10.6+. An older database may prevent future WordPress updates. Entry Plan detects the database version; Pro adds upgrade-readiness details, risk analysis, and recommendations.

PHP security notices

The plugin checks the website's PHP version against a list of known vulnerabilities. If it finds a match, the dashboard shows the vulnerability name and CVE and advises updating PHP or contacting the hosting provider. This notice is available to all customers without a license.

Set up and execute a scan

Install and activate Plugin Compatibility Checker in WordPress. To access Entry Plan results, subscribe through the CompatShield Portal, add your domain in the License tab, copy the license key into the plugin options, validate it, and save the settings. Then open the plugin's main page and click Rescan. Rescan after installing or updating plugins to include them in the check.

What Pro adds

Pro offers the full CompatShield Portal Dashboard, with detailed PHP analysis, database upgrade-readiness insights, vulnerability summaries, email notifications when scans finish or risks are detected, historical analysis, plugin issue and site overviews, and ZIP scanning for custom or premium plugins through the portal uploader.
