Captcha doesn't work correctly anymore.

I now have another captcha used for my blog posts. The stupid thing is that this captcha works well with the contact form.
It would be nice if someone could tell me why he did not work correctly in my blog posts.

Hello Renske-GK,

It is not clear, where the captcha doesn’t work. In the comments form or in the custom form?

Kind regards,
Support

By my blog posts or recipe posts. Guests could not respond to my blog (recipe) posts. They gave an answer to the captcha and they got an error message. I also tried myself and although you gave a correct answer you got an error.

I have now temporarily disabled and I use now temporarily another captcha and working properly. Only I would like to use your captcha.
The captcha does work correctly in the contact form, but the contact form does not work properly.

Because the problem with the contact form has not been resolved and removed, I also removed the captcha. Without contact form I have nothing to this captcha plugin.
This can also be closed.
