I have three sites that I'm adding CAPTCHAs to (www.hoekstratruck.com/index.php/contact, www.hoekstratransportation.com/index.php/contact, and www.hoekstraspecialty.com/index.php/contact/ctest). On the first two, the captcha works fine. It shows up and says that it is required to submit the form. On the third site, however, when I include the {if captcha} tag, nothing shows up. If I leave that tag out, just having
<p>Please enter the word you see in the image below:<br/>
{captcha}<br /> <input type="text" name="captcha" value="" size="20" maxlength="20" style="width:140px;" /></p>
it displays the prompt and the text box, but not the image (and it doesn't print "{captcha}" either). I have double checked that the server path and image html path are both correct.
All three sites are running off EE v1.7.1 and I don't see any difference in how the first two sites are set up compared to the third site.
Please help!
