I found this error in my log:

CAPTCHA problem: hook_captcha() of module ascii_art_captcha returned nothing when trying to retrieve challenge type ASCII art CAPTCHA for form user_register

What does it mean?

it means that the base CAPTCHA module asked the ASCII art CAPTCHA module to generate a challenge, but the ASCII art CAPTCHA module did not return anything.

Are there a lot of these entries in your log, or just one?

Did you check if the ASCII art CAPTCHA works on your site? Does it show up on the user registration page, does it block wrong answers, does it let pass right answers?

There's atleast 1 a day. I've never seen the issue myself. The ASCII art works just fine when I go to the page.

is there a pattern in when it occurs?
e.g. always at the same time, the same user, the same IP address, something?

actually it's occurring all of the time now. I'm going to uninstall and reinstall the module and I will get back to you.

Reinstalling the module seems to have fixed the problem. I'm not sure what happend, but I'm closing this isssue. I'll reopen if it starts happening again. Thanks for your help.
