📖 Plugin Compatibility Checker – Documentation
The Plugin Compatibility Checker helps you scan your installed plugins and themes to ensure they are compatible with the latest versions of PHP and WordPress. It also provides security insights such as plugin vulnerabilities.
🔧 Installation
1. Install the plugin from the official WordPress repository: Plugin Compatibility Checker
2. Activate the plugin from the WordPress Plugins page.
🔑 License Setup
1. Go to Plugin Settings → License.
2. Enter your purchased license key.
3. Click Save Settings and then Validate.
Without a valid license, scans will only show compatibility up to PHP 8.0. With a valid license, you can view compatibility results up to PHP 8.4.
🔍 Running a Scan
1. Open the Plugin Compatibility Checker main page in your WordPress dashboard.
2. Click Rescan. This will detect and list all installed plugins. Whenever you install a new plugin, click Rescan again to include it in the scan.
3. Wait for the scan to complete. You will receive an email notification once the scan is finished. Results are available in two ways: from your WordPress backend (fetch latest results) or from the CompatShield Portal.
📬 Fetching Latest Results
Click Fetch Latest Result to update your dashboard with the latest compatibility and vulnerability data from the Portal.
⚠️ Special Notes
Plugins showing No Data usually mean:
- It is a custom or premium plugin not listed on WordPress.org.
- The plugin version you are using has been removed by the author.
The plugin also checks for known vulnerabilities. In the Portal Dashboard, you can view both compatibility and vulnerability results for your domain.
