whisperwow first of all, thank you for donating! Also, thank you @luceos for replying in the meantime
As for the issues itself, I believe that they are related. It seems that, for some reason, the reCaptcha object is undefined, or its JS is not included at all:
Uncaught ReferenceError: grecaptcha is not defined
at e.getResponse (RecaptchaState.js:34:5)
at e.<anonymous> (extendSignUp.js:28:51)
at forEach.t.<computed> (extend.ts:39:16)
at forEach.t.<computed> (extend.ts:37:41)
at forEach.t.<computed> [as submitData] (extend.ts:37:41)
at n.onsubmit (SignUpModal.tsx:170:23)
at e.<anonymous> (extendSignUp.js:56:12)
at forEach.t.<computed> [as onsubmit] (extend.ts:86:24)
at O.handleEvent (render.js:888:55)
Do you mind if I create a temporary admin account and look into this for you?
