Hi. I have this problem at my website every time I log in and it includes something about reCaptcha. I have been receiving this error
"Login was unsuccessful. Please correct the errors and try again. The reCAPTCHA response is invalid or malformed. Please try again."
and I would like to just remove the reCaptcha or set it by default. Maybe you can help me or you can refer me to someone who can because I don't know how these things go.
For quick fixing, you can disable the reCaptcha for time being. To disable the reCaptcha go to your admin panel then Configuration==>General settings==>go to the CAPTCHA section at bottom of the page and disable it. For old site(3.4,3.5,3.6,3.7) it under Security settings tab. If you need long-term fixing, then you need to upgrade the reCaptcha version if it is old and need to give appropriate information.
