For some reason our customer login form on the frontend does not work anymore. We still can login into the backend without any problems.
I check the log files, but there are not error's displayed. Also there is no frontend error displayed.
Anyone a idea how to solve this problem?
EDIT: First it seems to be a CAPTCHA problem, I get the following error;
You cannot proceed with such operation, your reCaptcha reputation is too low.
After that we disabled the CAPTCHA on frontend and then we get the following error;
The account sign-in was incorrect or your account is disabled temporarily. Please wait and try again later.
Account and login details are correct, but it does not load. Also the customer account is not disabled or blocked.
Anyone a idea?
