So can you actually see the captcha preview?

Go to your ACP -> Quick access -> PHP information and scroll down until you see the GD section.

Do your settings look similar? If not, what are they?

We cannot see your problem in action if you have the captcha disabled.

Actually, sometimes installed GD does not work properly. I've got the same for our server, for example.

So... ask your provider to fix GD2. You can check if it works properly, if you upload an image with .jpg extension (with name "image.jpg"), at the same directory you upload and execute script like that:

Code: Select all

<?php
$path = "image.jpg";
$content_type = "image/pjpeg";
header("Content-type: ".$content_type);

$source = imagecreatefromjpeg($path);
imagejpeg($source, "", 100);
?>

Visual confirmation (also known as CAPTCHA) is meant to thwart automated registrations, used primarily to get an account on your board that can then be used to automatically post advertisement messages. AKA: spamming :) If you switch it off, prepare to get a flood of spam registrations before long. That said, there are reports that suggest phpBB's standard CAPTCHA has been compromised, so you might look into installing one of the alternatives, while you're at it.

Hi guys. While you're looking at this, I'm also expreiencing a similar problem - sort of. My problem is that the visual confirmation is not visible on some computers, but not all. CAPTCHA is enabled, and I can see it in the preview. I am also able to see it on my personal computer. But if I walk across the hall to someone else's computer, they can't see the CAPCTHA and only get the "red X".

I have checked the PHP information page, and don't appear to have any GD settings whatsoever. I'm not sure what GD is, but I don't see it anywhere on the page as displayed above. (I can post the entire page if you like). I'm not sure if I need "GD" or not. (???)

Is there a local setting for IE or something (activeX, or something like that) that is needed to view the visual confirmation?

FYI our forums are located here.here. Thanks.

You have edited language/en/common.php and saved it with encoding UTF-8(w/BOM)
You need to get a bettertext editor, such as Notepad++ and resave that file with encoding UTF-8(w/o BOM)
