#   ssh -p 2222 -i /path/to/your/private_key respon45@199.250.194.180

#   (1) If you copied this script to the server:
#       cd /home/respon45/responsabhealth.com && chmod +x scripts/debug-production-500.sh && ./scripts/debug-production-500.sh

#       ./scripts/debug-production-500.sh /home/respon45/responsabhealth.com /home/respon45/responsabhealth.com/web
#
# If your Apache/Nginx docroot points at the repo root (no web/), use:
#       ./scripts/debug-production-500.sh /home/respon45/responsabhealth.com /home/respon45/responsabhealth.com
