Captcha doesn't work

[Sunsi]

When someone wants to register, the captcha doesn't show. So the picture doesn't show but people are asked to fill it in. No matter what they do, it won't work. What can I do to restore it?

Then pick a different option

Captcha's are useless anyway. Many spam bots override that anyways.

You have to make sure your php has been compiled with the gd library installed and that the php version is compatible with the captcha code, just make sure gd library is installed first and see how you go :)

[ozzy47]

True, but they are still useless. :)

The best defence is to have many Q&A's

[ozzy47]

Not really, the harder you make it for legitimate users to sign up, the less you get.

Best way I have found is a bunch of different spam mods, all running together, http://ozzmodz.com/showthread.php/506-The-Era-Of-Big-Spam-Is-Over

And where do I do that? There are no other options with the Human verification options.

And where do I do that? There are no other options with the Human verification options.The native vBulletin human verification methods meet with either spotty success, or don't work at all. And that's not just vBulletin, but all the major email providers as well. Check the link in my signature when you're serious about stopping spam.

Captchas and other such gimmicks, puzzles, photo identification and so on, were defeated long ago. They're obsolete.

Try the mod in my sig.

Well, I didn't use captcha anymore on my forum and I was almost instantly flooded with spam, porn and other annoying threads. So, captcha does work. Now I've reinstalled but , but now new users can't register because captcha doesn't show.It's just a cross.
So how do I get captcha to work again? Thanks!

Did you try the mods in the post from my signature, http://ozzmodz.com/showthread.php/506-The-Era-Of-Big-Spam-Is-Over

Think about it - all the big email providers use it, but they still get bot signups and use of the accounts, by bots. You just haven't had the right botnet come along to hit you yet.

All it does even when working nicely is annoy legitimate people. It's obsolete. It's a cutesy gimmick that went the way of dialup.

Thanks everybody for taking the trouble to answer, but I only just want the captcha to work again. But nobody has said anything so far about how I can get the captcha to work again.
Apparantly, it does work for my forum. All I want to know is how do I fix the captcha.
What is wrong with it now? How do I fix it? Anybody got an answer to that?

Yes someone did, Simon told you in post #4 a possibility.

[Simon Lloyd]

Create a text file with the following code<?php
if (extension_loaded('gd') && function_exists('gd_info'))
{
echo "It looks like GD is installed";
}
?>save it as gdinfo.php, load it in your server then access it like www.mysite.com/gdinfo.php if you have gd library installed you'll get the message "it looks like GD is installed"

[Sunsi]

Thanks for that. I'm sorry I didn't see that. I'll look into that. :)
