I have the same problem.

The idea with reCAPTCHA is that you generate training data that is used to teach machine learning algorithms. This means that sometimes you'll be presented with data where the correct answer isn't known, and then you might need to answer a second question to check that you're reliable and trustworthy.

I have a couple of theories about what might be going on with the CAPTCHAs. Specifically, before, our setup looked like:

Internet -> phpBB forum

Now it looks like:

Internet -> nginx reverse proxy -> phpBB forum

The problem is that the phpBB software no longer sees Internet IP addresses, but now only sees the internal IP address of the nginx proxy. Usually, this should just work transparently, because nginx sets an X-Forwarded-For header with the real IP address, which phpBB is supposed to look at. But for whatever reason, I think phpBB normally ignores this. So this means that phpBB thinks that all users of the site come from the same IP address, which it probably why it's accusing random people of too many failed logins—all failed logins seem to come from nginx.

When I have a moment, I need to Google this issue and fix either our phpBB install or possible our nginx reverse proxy configuration to get X-Forwarded-For working again. Unfortunately, it's crunch time at work, and I'm pretty busy right now.

If somebody technical has some time to look into this, or even send a pull request, I'd be massively grateful. If not, I'll try to get to it as soon as I can.

emk, is that also the reason the main page always says there's exactly one guest user online?

Sorry to bring up an old issue and sound like a whiner, but these CAPTCHA questions are pretty annoying. Are we any nearer to a solution? :?

Please tell me if it's none of my business :|

No nearer a solution I'm afraid. Nobody has time to delve into the issue.

The spammers are pretty persistent. I think it's just how it is.

Mildly annoying, but far less annoying than spammers.

Thanks to the team for implementing a working solution. Very much appreciated.
