I built the site on a test server and the security image was working fine, now after restoring it to the proper server the image doesnt show up. the site is live so this is really urgent, very grateful for some help please:
www.onegolfcard.com/Create-an-account.html

thanks

Your image is trying to load from:

www.onegolfcard.com/components/com_comprofiler/plugin/user/plug_cbcaptcha/captchaindex.php?captchaurlmode=image&captchasid=H7yPc26xvX3Wk5XhcLcVBMzetRjcW2gJ

when I try to access that directly I get:

Fatal error: Call to undefined function imagettfbbox() in /home/onegolf/public_html/components/com_comprofiler/plugin/user/plug_cbcaptcha/captchasecurityimages.php on line 147

Looks like it can't find that function in captchasecurityimages.php line 147. Might want to start there to track down the issue.

thanks for the fast response, this is the code but i dont know what could be the problem ?

case 5:

$this->font = 'fonts/PRIMER.ttf';

break;

is there a fonts folder at www.onegolfcard.com?

is there a PRIMER.ttf font in that folder?

yes the folder structure is the same on test and live site - i have copied it across anyway but not made any difference.
thanks
