What are the requirements?

Securimage-WP requires PHP 5.2+, GD2, FreeType, and WordPress 3+. If you install Securimage-WP, there is a test script that will tell you whether or not your system meets the requirements.

The CAPTCHA image is not displaying

From the Securimage-WP settings menu, enable the Debug Image Errors option, save the settings, and then click the link labeled View Image Directly. Ideally, this will reveal any error messages that may be causing the image generation to fail. Try to troubleshoot the error, or contact us for assistance.

The refresh button does not work

Javascript must be enabled for the refresh buttons to work. Make sure Javascript is enabled or check for errors that may prevent it from functioning.

I noticed the image refresh by itself when I was looking at my comment form

CAPTCHA codes have expiration times in order to reduce the amount of time spammers have to break the CAPTCHA. The default time is 15 minutes. After this time lapses, the CAPTCHA refreshes since it is no longer valid. You can customize this setting in the options menu.
