CAPTCHA images not appearing

CAPTCHAs are enabling but there is a blank space where they should appear.

Troubleshooting missing CAPTCHA Images

There are several possible reasons for CAPTCHA images to not appear:

  • The path and/or URL to the CAPTCHA directory is not specified correctly under Admin ‣ Security and Privacy ‣ Captcha Preferences.
  • The images/captchas/ directory is not set to 777 (writable by a PHP-based application)
  • The server does not support True Type Fonts. TrueType Fonts can be disabled in Admin ‣ Security and Privacy ‣ Captcha Preferences.
  • GD library isn’t installed and/or working correctly
