Getting "invalid port/service error" for port 80

[jols]

Not sure what to look for here. Upon restarting CSF in shell, I am getting this error near the bottom of the output:

*ERROR* line:[2036]
Command:[/sbin/iptables -v -A INPUT ! -i lo -p tcp --dport "80 -m state --state NEW -m recent --set --name "80]
Error:[iptables v1.4.7: invalid port/service `80 -m state --state NEW -m recent --set --name 80' specified]
You should check through the main output carefully

I've checked though the csf.conf file carefully, yet I can't quite spot what might be causing this.

Thanks for any assistance.

Line 2036 in csf.pl would suggest an invalid PORTFLOOD string or setting.
