I’m not a dev. It was all working fine, and now it’s not. I don’t plan to hire a dev to fix things because you did an update that made a working plugin fail. If that’s what your answer is, then your captcha is worthless to me.
And as I already wrote, I’m not using a customer comment form. This is more work than your captcha is worth. If you want people to use it, then it’s your job to make it work, as it did for years.
