Sentinel Troubleshooting
This guide covers common issues specific to Sera Sentinel security features.
False Positives (Legitimate Traffic Blocked)
Firewall Blocking Admin Actions
Cause: The WAF may block certain admin actions that look like attacks (e.g., saving posts with HTML, uploading files).
Fix:
- Go to Sentinel > Firewall > Whitelist
- Add your admin IP address to the whitelist
- Or reduce the protection level from High to Medium
Firewall Blocking API Requests
Cause: REST API or AJAX requests may trigger WAF rules.
Fix:
- Check the Sentinel > Firewall > Log for blocked requests
- Identify the rule that triggered the block
- Add an exception for the specific endpoint or request pattern
Locked Out of WordPress
Via Brute Force Protection
Cause: Too many failed login attempts from your IP.
Fix:
- Wait for the lockout to expire (default: 30 minutes)
- Or access your site via FTP and rename the
sera-sentinelplugin folder to deactivate it - Log in and whitelist your IP address
- Rename the folder back to reactivate Sentinel
Via Custom Login URL
Cause: You changed the login URL and forgot it.
Fix:
- Access your site via FTP
- Open
wp-content/plugins/sera-sentinel/and find the settings file - Or rename the plugin folder to deactivate Sentinel and restore the default login URL
Malware Scanner False Positives
Cause: Some legitimate plugins use code patterns that look suspicious (eval, base64_encode, obfuscated code).
Fix:
- Review the flagged file in the diff viewer
- If the file belongs to a trusted plugin, add it to the Scanner > Whitelist
- If unsure, search for the file hash online to verify its legitimacy
Two-Factor Authentication Issues
Lost 2FA Device
Fix:
- Use one of your backup codes to log in
- Go to Sentinel > 2FA and reconfigure with your new device
- If you have no backup codes, access the database and clear the 2FA settings for your user
2FA Not Accepting Codes
Cause: Time sync issue between your device and server.
Fix:
- Ensure your phone's time is set to automatic
- Check your server's time is accurate (
datecommand in SSH) - Try using the next or previous code (30-second window)
