Posting comments on EDNA blog does not work

I cannot post comments on the EDNA blog. The captcha acts as a contraceptive. It always shows error “Error: You entered an incorrect CAPTCHA answer. Please go back and try again.” But I cannot even see a UI control where I could enter an answer, not to mention an incorrect answer. Could you please advice how I can post comments or fix this issue if it is a bug? I tried Edge and Chrome browser.

Thanks for the screenshot @Martin. Our team will look into this asap and will provide more details here soon.
