Captcha not working with Joomla 3.9.5

Hello,

since two days, I am facing a strange problem. It happened since the version 3.9.5.

The captcha is not displayed.
Please could you check the following page: Titlehttps://www.guillenphoto.com/cms/en/why-artistic-photography-is-subjective.html
Scroll to the bottom of the page. Instead the captcha I have "Komento Image".

I have a test website which is still running with the version 3.9.4. Everything is OK.
Please could you that page: Titlehttps://dev.guillenphoto.com/cms/en/why-artistic-photography-is-subjective.html

Same page but in the test website.

Please would you help me to solve the problem?

regards
A. Guillen
