OK. I looked at the source code in my install and it is JavaScript what adds the custom fields. Go to your General Settings page and look for this code, see if it's there.
- Code: Select all
<div id="ws-plugin--s2member-custom-reg-field-configuration"><div id="ws-plugin--s2member-custom-reg-field-configuration-tools"><a href="#" onclick="ws_plugin__s2member_customRegFieldAdd(); return false;">Add New Field</a></div>
Your blog seems to be changed by GoDaddy to display their ads, if you have the same thing happening in the admin area, maybe that's what's affecting the proper function of the JavaScript for the interface.
