Can I use Captcha PLUS for Wordpress login and registration forms? I want to stop spam registrations on my blog.

Yes. Captcha PLUS can be used for Wordpress login, registration, lost password, comments and contact form. To secure your website from spam and spam bots we recommend to use Captcha with additional plugins such as Contact Form and Limit Attempts.

I have some problems with the plugin’s work. What Information should I provide to receive proper support?

Please make sure that the problem hasn’t been discussed yet on our forum:

If no, please provide the following data along with your problem’s description:
  1. the link to the page where the problem occurs.
  2. the name of the plugin and its version. If you are using a pro version – your order number

How to change a captcha label?

You should go to the Settings page and change the value in the ‘CAPTCHA label in the form’ field.

During the settings saving I get the error: ‘Please select one point in the blocks “Math actions” and “Complexity Level”‘. What is this?

For stable work of the Captcha plugin you should select at least one item in the ‘Math actions’ block and select ‘Complexity Level’ on the Settings page, because math expression should consist of at least 1 math sign and parts of math expression should be displayed like words or numbers or both of them.

Missing CAPTCHA on the comment form?

You might have a theme where comments.php is not coded properly. Wordpress version matters.

(WP2 series) Your theme must have a tag

<?php do_action('comment_form', $post->ID); ?>

inside the file

Most WP2 themes already have it. The best place to put this tag is before the comment textarea, you can move it up if it is below the comment textarea.

(WP3 series) WP3 has a new function comment_form inside of


Your theme is probably not up-to-date to call that function from comments.php. WP3 theme does not need the code line
do_action('comment_form'... inside of /wp-content/themes/[your_theme]/comments.php
Instead it uses a new function call inside of comments.php:
<?php comment_form(); ?>
If you have WP3 and captcha is still missing, make sure your theme has
<?php comment_form(); ?>
inside of
(please check the Twenty Ten theme’s comments.php for proper example)

How to use the other language files with CAPTCHA?

Here is an example for German language files.
  1. In order to use another language for WordPress it is necessary to set a WordPress version to the required language and in the configuration wp file –
    in the line
    define('WPLANG', '');
    you should enter
    define('WPLANG', 'de_DE');
    If everything is done properly the admin panel will be in German.
  2. Make sure the files `de_DE.po` and `` are present in the plugin (the folder “Languages” in the plugin root).
  3. If there are no such files you should copy the other files from this folder (for example, for Russian or Italian) and rename them (you should write `de_DE` instead of `ru_RU` in both files).
  4. The files can be edited with the help of the program Poedit – – please download this program, install it, open the file using this program (the required language file) and for each line in English you should write translation in German.
  5. If everything is done properly all lines will be in German in the admin panel and in the front-end.

  2. Go to “Contact Form 7″ form where you want to make use of Captcha.
  3. Find a dropdown menu with the form fields, select BWS CAPTCHA and insert it into your form.

I would like to add Captcha to the custom form on my website. How can I do this?

  1. Install the Captcha plugin and activate it.
  2. Open the file with the form (where you would like to add captcha to).
  3. Find a place to insert the code for the captcha output.
  4. Insert the necessary lines:
    if( function_exists( 'cptch_display_captcha_custom' ) ) { echo "<input type='hidden' name='cntctfrm_contact_action' value='true' />"; echo cptch_display_captcha_custom() }; if( function_exists( 'cptchpr_display_captcha_custom' ) ) { echo "<input type='hidden' name='cntctfrm_contact_action' value='true' />"; echo cptchpr_display_captcha_custom() };
    If the form is HTML you should insert the line with the PHP tags:
    <?php if( function_exists( 'cptch_display_captcha_custom' ) ) { echo "<input type='hidden' name='cntctfrm_contact_action' value='true' />"; echo cptch_display_captcha_custom(); } if( function_exists( 'cptchpr_display_captcha_custom' ) ) { echo "<input type='hidden' name='cntctfrm_contact_action' value='true' />"; echo cptchpr_display_captcha_custom(); } ?>
    Then you should add the lines to the function of the entered data checking
    if ( ( function_exists( 'cptch_check_custom_form' ) && cptch_check_custom_form() !== true ) || ( function_exists( 'cptchpr_check_custom_form' ) && cptchpr_check_custom_form() !== true ) ) echo "Please complete the CAPTCHA.";
    <?php if ( ( function_exists( 'cptch_check_custom_form' ) && cptch_check_custom_form() !== true ) || ( function_exists( 'cptchpr_check_custom_form' ) && cptchpr_check_custom_form() !== true ) ) echo "Please complete the CAPTCHA." ?>
    You could add this line to the variable and display this variable in the required place instead of echo “Please complete the CAPTCHA.”. If there is a variable (responsible for the errors output) in the check function, this phrase can be added to this variable. If the function returns ‘true’, it means that you have entered captcha properly. In all other cases the function will return ‘false’.
