Frequently asked questions
Quick answers about how to use WPShieldJournal safely.
Do your tools scan or access my website?
No. The troubleshooting finder and checklists run entirely in your browser. They cannot see your site, and nothing you select or tick is sent to us. Checklist ticks are stored only on your own device.
Will you ever ask for my WordPress password?
No. None of our guides or tools need your WordPress, hosting or database passwords, or the secret keys in wp-config.php. Be cautious of anyone who asks for them without a clear need.
My site is down right now. Where should I start?
Start with the troubleshooting finder and pick the symptom you see. If you see “There has been a critical error”, check the site admin email inbox for a recovery link. If you cannot fix it quickly and the site earns money, contact your host or a developer.
How often should I back up my WordPress site?
Match the schedule to how much you could afford to lose: weekly for quiet sites, daily or more for busy sites and shops, and always before updates or migrations. Keep at least one copy away from your web server and test a restore now and then.
Are the steps safe to follow on a live site?
Each guide marks risky steps and tells you what to back up first. Changes to plugins, databases or code are safest on a staging copy. If a step does not match what you see, stop and check before continuing.
Can I suggest a topic or report a mistake?
Yes. Use the contact page to suggest a guide or point out an error. We cannot log in to your site or provide emergency support, so for urgent problems contact your host or a developer.
