[Plugin: SI CAPTCHA Anti-Spam] captcha not appearing at all

> I am guessing it is because the theme uses a custom sign-up page?
yes

Try adding the same do_action and apply_filters the original registration page had. If that does not work I can’t help you because you have modified the WP files.

do_action('register_form');

$errors = apply_filters( 'registration_errors', $errors, $user_login, $user_email );

crs1138,

What version is your WordPress?

It could be a theme causing it…
Do this as a test:
Activate the SI CAPTCHA plugin and change your theme to
the “WordPress Default” theme.
Log out of Admin and test the captcha as a normal user.
Does the captcha work properly now?
If it does then the theme you are using is the cause.

When diagnosing missing CAPTCHA field on comment form….
The version of WP makes a difference…

(WP 2 series) Your theme must have a
<?php do_action('comment_form', $post->ID); ?> tag inside your comments.php form. Most themes do. The
best place to locate the tag is before the comment textarea, you may
want to move it if it is below the comment textarea.

(WP 3 series with a proper WP3 theme does not need this step, but if you have WP3 update to plugin version 2.5.2 or higher, if you still have the missing captcha, try above WP Series 2 steps)

Sorry my mistake, I was checking it while logged in as admin. It works just fine. Thanks again.

Still I’d be interested if there is any way, how to get the CAPTCHA to work with forms on the page? These are actually, where the most of the spam comes from. I’m using a plugin Contact Form 7 v2.4.1 to generate the plugins.

Thanks Mike, but my form has bit more fields, it’s kind of a survey, rather than just a contact form.

I’m sorry, but the same 🙁

WP version 3.0.1
PHP version 5.0

After activating plugin there is the picture:
