Zoo Visitor Registration Error

Question

I'm using Zoo Visitor and when a user tries to register, they get this error:

You must be a logged-in member of this site in order to perform this action.

I'm not sure what is causing it...?

Here is my registration form...

{exp:zoo_visitor:registration_form class="form form-validate" return="account/register/success"}
<ul>
    <li class="required">
        <label>First Name</label>
        <input type="text" name="cf_member_first_name" value="">
    </li>
    <li class="required">
        <label>Surname</label>
        <input type="text" name="cf_member_surname" value="">
    </li>
    <li class="required">
        <label>Email</label>
        <input type="email" name="email" value="">
    </li>
    <li class="required">
        <label>Password</label>
        <input type="password" name="password" value="">
    </li>
    <li>

    </li>
    <li>
        <input type="submit" name="submit" value="Register &rarr;">
    </li>
</ul>

Answer 1

Go to Add-ons --> Modules --> Zoo Visitor --> Troubleshooting, it should be there.

[edit]:

In Add-ons --> Modules --> SafeCracker, always check to see if anonymous registrations are allowed.

Answer 2

Are you sure that user is already logged into the CP when they try to register via the Zoo Visitor form on the front-end?

Make sure you are logged out of the CP, or better yet try another browser to complete the registration.
