 * This morning, i woke to find that visitors are not able to register on this site
   and they are receiving this error, Undefined error. Key: browser-error. I’ve 
   gone through the settings and compared them with another site with similar settings
   and can NOT understand what the issue could be. Help please. I’m on php 8.0, 
   WordPress 6.1.1.
 * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fundefined-error-key-browser-error%2F%3Foutput_format%3Dmd&locale=en_US)
   to see the link]_

   error?

 * What happened was that my recaptcha secret and public code was not the right 
   one for that website. I have been building on 3 sites at the same time and I 
   entered the wrong info. So, try checking your code to ensure that it’s correct.
   Also, if you’re using a staging site, make sure that you enter the staging site
   address into the Google Recaptcha settings for that site.
