How do I restore City, County, State to the Address block in Contact Summary
If the problem is that the county does not show up with viewing the address on the contact summary page... You can control what address fields are displayed by clicking Adminster -&gt; Localization -&gt; Address Settings.

Then, find the Address Display Format field and add to it: {contact.county}

If the problem is that when you edit the address, no county field shows up, then you can choose which fields show up by clicking Adminster -&gt; Localization -&gt; Address Settings.

Then, find the Address Editing field and check off the county option.

If the problem is that the county option is not even an option for Address Editing, then click Administer -&gt; System Settings -&gt; Option Groups. Find Addressing Options and clicked Edit Option. Hopefully county will be listed but disabled and you can simply enable it. If it's not there at all you could try adding it, but I'm not sure if it will be added in a way the CiviCRM expects.
