No reCaptcha in Comment (has installed fix plugin)

Hello.

reCaptcha does not appear in my ClassiPress theme’s comment section.
The reCaptcha successfully appears on the login page.

I have installed fix plugin here

I have toggled “My Comment Form is WordPress 4.2 compatible.” both on & off.
It still does not appear.

What template / code should i check?

Thank you.
