Website Troubleshooting: iptables Misconfiguration

I urgently need help restoring access to my website which has been down due to some iptables rules misconfiguration. Crucial details about the specific changes made to the iptables configuration are not available but I can provide access to the server for a professional to diagnose and fix it.
