# [Plugin: cforms v9.2] Captcha image doesn’t display!

 * I just downloaded and “manually” installed / uploaded cforms 9.2 to my Web server
   for the first time yesterday, and I can’t get the Captcha Visitor Verification
   option to work properly (i.e., the Captcha image doesn’t display) no matter what
   I do.
 * The problem seems to be in the cforms-captcha.php file per the following cforms
   error log entry, viz:
 * > [11-Nov-2008 13:28:07] PHP Fatal error: Call to undefined function imagettfbbox()
   > in /home/freeblog/public_html/magnetic-marketing-group.com/wp-content/plugins/
   > cforms/cforms-captcha.php on line 80
 * I looked at the file to see what it was referring to, but I’m not a programmer,
   so I don’t know how to fix this issue.
 * FYI: I’m running WordPress 2.6.3 with PHP 5.2.6 and MySQL 5.0.51a-community. 
   And I have followed all of the related suggestions in the cforms FAQ / forum 
   and made the recommended changes, accordingly.
 * Moreover, I’m able to use the cforms Q&A Visitor Verification method, which is
   OK. But I would like to use the Captcha option as well. Any help on this matter
   would be greatly appreciated & thanks in advance.

 * …believe it or not this is the issue 😉
 * check with your hosting company, perhaps they can enable **imagettfbbox()**

 * So you’re saying that **imagettfbbox()** is a common PHP function that needs 
   to be enabled on the server side. OK, I’ll try it… Thanks for the input!
