How can I delete my address and change my telephone number?

It looks like that is widget in the footer- so see if you can find it under Appearance >> Widgets

Okay. I looked there and I see on the sidebar it says Footer Column 5 (Contact) , but when I click on the arrow it say custom widgets.

Where did your site come from?

I don’t understand. It was created from WordPress 3.5.1

The theme is The Canyon. If you mean that

Yes, that’s what I meant – it looks like you are using this commercial theme: https://themeforest.net/item/the-canyon-wordpress-theme/92130

If so, you’ll need to ask the developer for help – as we don’t have access to commercial themes.

There’s a theme here by the same name https://www.ads-software.com/extend/themes/canyon but that doesn’t appear to be the same theme – but that’s why I was not sure.

Oh okay. Thank you for your help.
