It's activated but I don't know why don't appear the box when someone will register.
Example:

I can register without problems, but I have a few problems with some bots... Also I don't want to use another plugin, just the default captcha for MyBB.
ACP >> Board Settings >> General Configuration >> scroll down and find CAPTCHA Images for Registration & Posting >> and click the yes box.
How I said in the first post is activated.
Then open: member_register template and find is "{$regimage}" present. ?
Is {$regimage} in your member_register template, and is the member_register_regimage template default?? If they both are, make sure ./inc/settings.php is CHMOD to 666, and if it is, try just saving the settings again.
1. Yes it is.
2. Yes is the default.
3. was 777, changed to 666, saved again and nothing happens.
I was thinking that was the skin, but no I tested in a older one and happen the same thing :l
Also tested in English lang.
Put this in a file called captchatest.php or something, upload it to your server, and view it, what does it output??
<?php
var_dump(function_exists("imagecreatefrompng"));
?>
That's why then, it hasn't got the function available to create the image. If it did work and no suddenly doesn't, your host must have changed something.
