CAPTCHA images are being created with 600 permissions

Thanks for the detailed explanation! I was running into the same issue with captcha image permissions set to 600, and your post helped me pinpoint the problem. For anyone else troubleshooting stuff like this, I’ve been using DeepSeek to assist with debugging code and server config, it’s been surprisingly helpful, especially when you’re stuck on something like file permissions or script behavior. Just thought I’d share in case it helps someone else here too.
