Hi,
I tried the plugin “SI CAPTCHA Anti-Spam” (https://wordpress.org/extend/plugins/si-captcha-for-wordpress/), but it is not working for me.
I have configured the plugin for add new topic and add new reply forms. Captcha appears, but even after entering correct captcha, it is showing an error message “ERROR: Unreadable CAPTCHA token file”.
Can anybody help?
