Frequently Asked Questions

Common questions about PreFlight Scanner

No. PreFlight Scanner performs static analysis only — it reads and parses PHP files as plain text without executing them. The ZIP is opened entirely in memory using PHP's ZipArchive. No files are extracted to disk.

Yes. Warnings are advisory — the plugin may still work correctly on your site. The scan results give you the information to make an informed decision.

You can, but a confirmation dialog warns you strongly against it. Critical issues typically mean a PHP fatal error is guaranteed on activation.

No. PreFlight Scanner is a pre-installation tool. To audit an already-installed plugin, deactivate it, download its ZIP, and upload that ZIP for scanning.

Scan results and the temporary staging directory are automatically deleted after 5 minutes. If you close the browser mid-scan, leftover data is cleaned up on the next page load.

Yes. The scanner is fully read-only. It never modifies any plugin files, settings, or database values outside of its own short-lived transients.

The Tools → PreFlight Scanner page requires the install_plugins capability, which is reserved for Administrators by default.

Hooks that every WordPress install registers many callbacks on (init, wp_head, admin_init, etc.) are excluded from hook-conflict reporting to avoid noise. The conflict check focuses on non-core hooks — plugin-specific filters, WooCommerce hooks, and other hooks where a collision is genuinely surprising.

The ZIP is read entirely in memory and never written to disk. PHP's standard file upload handling manages the temporary file and deletes it automatically at the end of the request.
