# TROUBLESHOOTING CSRF issues ("CSRF token missing or invalid" errors):
# 1. SECRET_KEY changed? All CSRF tokens become invalid when SECRET_KEY changes
# 2. Cookies blocked? Check browser settings and allow cookies from your domain
# 3. Behind a proxy? Ensure proxy forwards cookies and doesn't strip them
# 4. Token expired? Increase WTF_CSRF_TIME_LIMIT (in seconds)
# 5. Multiple app instances? All must use the SAME SECRET_KEY
# 6. Clock skew? Ensure server time is synchronized (use NTP)
# 7. Still broken? Try: docker-compose restart app
# 8. For testing only: Set WTF_CSRF_ENABLED=false (NOT for production!)
# See docs/CSRF_CONFIGURATION.md for detailed troubleshooting
