How to Fix Website Security Errors in WordPress

Are visitors seeing warnings like “This site is not secure,” “Your connection is not private,” or “Malicious content detected”? These website security errors can scare off users and hurt your SEO rankings. Fortunately, most are easily fixed with a few simple steps in WordPress and cPanel.

Here’s a guide to resolving common security-related issues and improving your site’s trust level.

Common Website Security Errors in WordPress

- “Your connection is not private” (SSL misconfiguration)
- “Deceptive site ahead” (flagged by Google Safe Browsing)
- “This site contains harmful programs” (malware)
- “This site can’t provide a secure connection” (TLS mismatch)
- Browser padlock missing or red

Step-by-Step Guide to Fix Security Warnings

1. Install and Configure SSL

An SSL certificate is required to serve content over HTTPS.

- In cPanel > Security > SSL/TLS or Let’s Encrypt
- Install an SSL certificate for your domain (most hosts offer free AutoSSL)
- In wp-config.php, force HTTPS:

define('FORCE_SSL_ADMIN', true);

- Update WordPress URL in Settings > General to start with https://

2. Force HTTPS via .htaccess

Redirect HTTP to HTTPS using the following in your .htaccess file:

RewriteEngine On
RewriteCond %{HTTPS} off
RewriteRule ^(.*)$ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]

3. Fix Mixed Content Errors

Mixed content errors happen when some site resources still load over HTTP.

- Use the “Really Simple SSL” plugin to automatically fix them
- Or search and replace URLs in the database using “Better Search Replace”

4. Scan for Malware or Hacks

Malicious code can trigger browser warnings and blocklist your domain.

- Use plugins like Wordfence, Sucuri, or MalCare to scan for infections
- Check Google Search Console > Security Issues for flagged content

If infected, clean the files manually or use a malware removal service.

5. Clean and Harden Your WordPress Site

After cleaning malware, prevent future attacks:

- Use strong passwords and enable 2FA (Two-Factor Authentication)
- Install a security plugin (e.g., iThemes Security, Wordfence)
- Remove unused themes, plugins, and old admin accounts

6. Update Everything

Outdated software is a common attack vector.

- Update WordPress core, themes, and plugins regularly
- Enable auto-updates or schedule regular maintenance

7. Check for Phishing or Spam Content

If your site was hacked and used for phishing:

- Review your posts, pages, and comments for suspicious links
- Clean up any hidden iframe, redirect, or JavaScript injections

8. Request Review from Google or Browsers

Once cleaned, go to:

- Google Search Console > Security Issues > Request Review
- Report false positives to your web browser security vendors if applicable

Final Thoughts

Website security errors can severely damage your site's reputation—but they’re often preventable or fixable. With SSL, regular scans, and cPanel access, you can clean up and lock down your WordPress site quickly.
