Firewall -> Rules No access

[tomast]

Hello,

Sorry for my english.
I am newbie to Pfsense.
I clicked on Firewall, Rules and after I changed the first parameter of the list.
It was the list of ports Pfsense, I think (80 and 22)
I changed to HTTPS. It worked. But after I chose HTTP and I validated.
And now,  when I click Firewall Rules, I can not access.
Other functions are ok.

How do I reactivate this feature?

Thank you for your help
