Ticked check box for emails

I am reviving s2member after not using it for a while. Unfortunately the ‘I want to receive updates by email’ ticked check box appears in the registration form. I want to remove this, but how.

Looking at the ‘Page Source’ code includes:

Yes, I want to receive updates via email.

Help to remove this will be appreciated.

Unfortunately the source code does not appear in my message above, so I will try with part of it:

label for=“ws-plugin–s2member-custom-reg-field-opt-in”, input type=“checkbox” …name=“ws_plugin__s2member_custom_reg_field_opt_in” value=“1” checked=“checked”
