Hello!
We do see that the Google reCaptcha does show up in Firefox but does not show up in Google Chrome. We’re getting the following JavaScript error generated by Google’s reCaptcha script:
reCAPTCHA couldn’t find user-provided function: recaptchaCallback
Upon inspection of the page source we were unable to find the google-recaptcha script which needs to be enqueued. This reCaptchaCallback should be included in wp_footer() as an inline script.
Do you have any caching plugins installed or are you using any server caching? If so, could you provide which caching tools you’re using? A possible solution may be to just clear the cache.
Otherwise it may be a plugin conflict. We would suggest installing the WordPress Health Check Plugin which will allow you to safely ( and for your logged in user ) disable plugins until you come across the plugin causing the issue. The Health Check Plugin also allows you to switch themes to the default theme ( again, just for your logged in user ) to see if it’s possibly a theme conflict.
