a) What part of the product isn't working?
In registration form, ALL the required fields (exception for username, email and password) can be empty and it is not blocking the account creation and thus the registration. There is an alert but no problem if the client wants to register without filling-in. It directly goes to "after login/registration redirection" page.
b) What are you trying to achieve?
I need my clients to absolutely confirm several required fields BEFORE the account creation. But at the moment it is not possible. You can see at the end of my registration form that there is a checkbox about a French law* (required field) + term and conditions** (required field). If there are not selected and checked, the registration is done anyway.
I must add that the translation of Terms and conditions is not "Termes et conditions" in French, but "Conditions générales de vente". It could be interesting to correct.
c) What causes the error to show up?
I do not know, it is a bug because in the parameters, the checkbox of my required custom field is well selected. The option "required" is validated and so should be considered during the registration step.
d) What version of the plugin are you using?
the latest I guess (I bought last week)
e) Provide a link to the exact page where the problem is seen
[marymann.fr/e-boutique/formulaire-enregistrement-client/]
f) Which product you are using (example: eStore, WP Affiliate Platform, eMember, PDF Stamper etc...)? eMember
g) Did you modify the plugin code? NO
