SafeCracker Not Working?

Question

I'm trying out SafeCracker for the first time. What I've done:

• SafeCracker module is installed
• Channel {test_profiles} is created with 1 field: {full_name}

The following code outputs nothing between the tag pair:

<h1>Hello World</h1>

<form>
    {exp:safecracker channel="test_profiles" datepicker="no" include_jquery="no" return="registration/form" safecracker_head="no"}
        <input name="title" type="text">
        <input name="full_name" type="text">
        <input type="submit" value="Submit">
    {/exp:safecracker}
</form>

Any ideas what might be wrong?

EDIT 1: I went to Addons -> Modules -> SafeCracker. I saw a list of my Channels there, including test_profiles. I checked the "Allow guests to post entries?" checkbox and selected one of the members from the "Set the member_id to use for guests." drop down menu. Afterwards, I viewed the template output again. Now I see a <script> and <style> inside the <form> tags. I still don't see my text field, though.

Answer 1

Does the member group have permission to post to the channel?

CP Home > Members > Member Groups > Edit Member Group > Channel Assignment

This part of the docs should help you allowing guests to post:

It certainly helps me to create a "Logged Out Members" member_group and a single user in that group to take ownership of those entries. (In my case their member_id is '2' as shown in tag example)

My tag looks a little like this:

{exp:safecracker channel="registrations"
                 return="foo/bar/ENTRY_ID"
                 logged_out_member_id="2"
                 ...
                 ...

My CP Home > Extensions > SafeCracker entry looks like this
