I tried to login through admin panel for one of my Magento site but it is showing error as
ERROR for site owner: Invalid key type - recaptcha and not able to login.
Actually I changed the google recaptcha keys values of existing project from v2 to v3 for contact page after that only I am not able to login.
Also customer view of the site is also blank
Please help to overcome this issue as I am new to magento.
