Installed, not having much luck changing themes. Is that theme dropdown suppose to work?

Edit: Ok, I tried the 3 themes and the only that shows for me is that butt-ugly red one. :p

If you're having a problem with themes, chances are the automatic template edit isn't taking effect. Simply make the edit manually.

In the register template:

• FIND:
  
  HTML Code:

  ---

                          $imagereg

  ---

  REPLACE WITH::
  
  HTML Code:

  ---

                          <script type='text/javascript'>
                        var RecaptchaOptions = {
                          theme : "$vboptions[recaptcha_theme]",
                          tabindex : $vboptions[recaptcha_tabindex]
                        };
                        </script>

                        $imagereg

  ---

And, just for good measure you might want to disable the automatic template edit plugin. In AdminCP > Plugins & Products > Plugin Manager look for Automatically modify register template (located under reCAPTCHA!vB) and uncheck the box, then click "Save Active Status".

That should do it!

Thank you for posting instructions here on how to make captcha work for guest using "Contact Us" form.

Works great and thanks again. :)

Would be absolutely great if this could also be used by registred users for things like replies, quick replies, new threads, etc. Even better if it could be used for registered users with less than x postings to their credit. So that it will help drive those manual spammers away.

Why would you want registered users to be subjected to CAPTCHA's?

I think that I followed all of the instructions but when I click on "register" it does go to /register.php but its blank. I replace it with the original and its ok. I did the upload etc. and added the keys to the product in the appropriate spaces. I have double and triple checked my typing. Any suggestions?

Thanks

// Check Reg Image
if ($vbulletin->options['regimagecheck'] AND $vbulletin->options['regimagetype'])
{
$resp = recaptcha_check_answer ($vbulletin->options['recaptcha_privatekey'],
$_SERVER["REMOTE_ADDR"],
$_POST["recaptcha_challenge_field"],
$_POST["recaptcha_response_field"];

if (!$resp->is_valid)
{
$userdata->error('register_imagecheck');
}
}

if ($vbulletin->options['regimagecheck'] AND $vbulletin->options['regimagetype'])
{
$imagereg = recaptcha_get_html
($vbulletin->options['recaptcha_publickey'],
$error);
}
else
{
$imagereg = '';
}

You're missing a close bracket ')' in the following block (highlighted in red):
Also, why are you typing out the code changes manually? Just copy and paste them from the original post to make sure there are no typo's and to retain proper formatting.

Thanks for your help, I knew that it was something stupid. Works great now. I guess that it was midnight, that I didn't think to cut & paste.

Love this method, love this hack, works flawlessly so far, and much more in keeping with my board ^^

Go you!

Glad you like it! :)
