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 > Captcha Preferences
- images/captchas/ directory is not set to 777/writable
- The server does not support True Type Fonts. TrueType Fonts can be disabled in Admin > Captcha Preferences
- GD library isn't installed and/or working correctly
