I have an issue with my contact form '(Fast and Secure SI Contact Form), Even if I write the good Captcha code, my form always returns this error message :
Could not read CAPTCHA cookie. Make sure you have cookies enabled and not blocking in your web browser settings. Or another plugin is conflicting. See plugin FAQ."
I've tested it with 5 internet browsers ! It's always the same !
It's not a cookies issue, I've un-installed plugin "Fast and Secure SI Contact Form" + "Wp-Re-captcha" (I use it for comments), but it's always the same !
