2026 Support Update: Imagick on WHM/cPanel for WordPress Checklist

Current action path: Imagick work is not done until uploads, thumbnails, media editing, PDF/image handling, PHP version, and rollback notes are verified.

What to verify before production changes

  • Confirm the site PHP version and extension availability before changing production.
  • Back up first, then test wp-admin, media uploads, forms, WooCommerce, and cron.
  • Document the rollback path if a plugin or theme breaks after the extension change.

Source-backed references and next reads

For support tickets, keep the exact system touched, backup timestamp, changed setting, public URL, and post-change verification result in the notes. That is the difference between a tutorial and an operational recovery path.
