Hi

I used to have this page - http://www.petenetlive.com/Captcha/captcha-page.php
handle access from my webmail form.

Recently I moved from a hosted server to my own, at this point I noticed that the capcha image was not displaying - Its been a few years since I installd that and Id forgotton how I set it up so I tried another one http://www.petenetlive.com/_capcha/index.php

same problem.

I've installed php on my Web Server  - What else do I need to do?

other php pages work like this.

help?

It's probably only a matter to have the right path in your src attribute of your image.

So the first question is, if the php file you're calling to generate the captcha is in the /_capcha Folder?

Where is this file located? Then adapt the src attribute accordingly.

Hi
Please share your code captcha.php or check log Apache.

Probably you have a different version of PHP on this server and script (captcha.php) throw some errors, warning, ...

add this on top of your index.php / capcha-page.php
and see the output:

<?php

error_reporting(E_ALL);

?>

Not the server modules I meant.

php --version (5.1, 5.2, 5.3, 5.4, 5.5 ) :)

Log is based on the distributions in different locations, eg / var / log / apache or httpd / error_host.log

Add to http://www.petenetlive.com/Captcha/captcha-page.php
error_reporting(E_ALL);
- suggestion "by: mcnute" is OK or find log on your distribution server.

'--without-gd'  you use gd to generate images in your script  ?

Maybe this is problem.

For RedHat - log is locate default in :
 /var/log/httpd/error_log
