PROBLEM

Unable to cleanup old CAPTCHAs

Recommended CAPTCHA directory to create and use: /some/server/homepages/22/123456/htdocs/joomla/captcha

Recommended CAPTCHA URL to use: http://your.domain.com/captcha

 

SOLUTION

You have not correctly configured the Directory to Write Captchas settings in the module configuration advanced options.

Look at the suggestion in the error message which says Recommended CAPTCHA directory to create and use.

This is the recommended directory you will need to create using the file system tools provided by your web hosting provider.
