Installation troubleshooting
Check extensions, permissions and document root.
- Enable missing PHP extensions in Plesk PHP Settings.
- Ensure the subscription PHP user can write private/var and public/uploads. Do not use permission 777.
- If styles or images fail, verify the infoweb/public document root and that extraction completed.
- Visit /install.php before looking for private/var/site.sqlite.setup-key. Keep the key outside the public directory.
- Do not delete an existing database to reinstall. Back up first and use an empty directory. Inspect Plesk error logs for details.
