Mantis Bug Tracker - Forums

Looking at the version of mantis at mantisbt.org/bugs shows that captchas are in use when signing up for a new account.

On my local installation, which has been upgraded to 1.1.5, captcahs are _NOT_ in use, yet a few greps from the code show that captchas are definitely possible.

Where do I turn on captcha use? Is there a GUI-accessible switch/flag I can set? Do I need to edit a configuration file somewhere? Do something via the admin directory? My apologies -- my understanding of exactly how to configure Mantis is weak and I'm not quite sure where I should go to get definative answers as I've found documentation online in previous attempts that seemed out of date.

Most mantis configuration is done through setting configuration options, either via the Mantis interface or the config_inc.php file.
Here is the relevant option from the config_defaults_inc.php file:
# use captcha image to validate subscription it requires GD library installed
$g_signup_use_captcha = ON;

It looks like it is on by default in 1.1.2.
Check your config files and edit if necessary (don't edit the defaults, options in config_inc.php override the defaults, so use that file).
You can also configure options via the "Manage -> Manage Configuration" page.
