recaptcha not showing up

Same problem.
I got this problem on multiple sites using this plugin. The following error is logged:

Refused to apply style from ‘https://www.gstatic.com/recaptcha/api2//styles__ltr.css’ because its MIME type (‘text/html’) is not a supported stylesheet MIME type, and strict MIME checking is enabled.
anchor:175 GET https://www.gstatic.com/recaptcha/api2//recaptcha__de.js 404 ()
anchor:1 Refused to execute script from ‘https://www.gstatic.com/recaptcha/api2//recaptcha__de.js’ because its MIME type (‘text/html’) is not executable, and strict MIME type checking is enabled.
anchor?ar=1&k=6Lcw&co=aHR0cHMz&hl=de&v=anonymized&size=invisible&cb=yxg:179 Uncaught ReferenceError: recaptcha is not defined
at anchor?ar=1&k=6Lcw&co=aHR0cHM6Lyz&hl=de&v=anonymized&size=invisible&cb=yxgljx:179

Seams that the Google API has changed and the plugin can’t handle the changes. Contact Form 7 integration for recaptcha still works fine.

Please release an update for the plugin!

I’m getting the same issue. Same error message. Oddly it only happens on SOME sites (eg. https://www.sarahmckenna.ie/wp-login.php) but not on others (eg. https://www.slated.ie/wp-login.php), even though they are all at the same WP and plugin version.

I must apologize. It is actually another similar plugin I am having the issue with. Sites using your plugin are all working fine.
