Hi
1. how change/manage the “Our Services” and “Quick Links” links list in the footer –
Go to Appearance >> Menu >> Here you can create menu name “Qucik Links” and add some pages and check the bottom checkbox as theme location:footer and then go to Appearance >> Widget >> Add custom menu widget in footer column and select quick link menu from dropdown.
2. how to change labels of personal contacts (email, address,…) in form in Contacts page
Are you using contact form 7?
Thank You
