Canvas theme How to modify "Quote" format

Unfortunately, we don’t have access to commercial themes, so can’t really answer theme-specific questions. You’ll need to ask WooThemes about this.

I think that Canvas theme don’t support Post Format… ??

I’m sorry but as you are using a non-WPORG theme, you need to seek support from the theme’s developers – paid or otherwise. We only support themes downloaded from www.ads-software.com here. Try https://www.woothemes.com/support/

It’s supported, Orsp, https://pellegrinifoundation.org and Canvas claims that eery element in the theme is customizable, but I’ll be darned if I see how to customize this one. Thanks, for your note.
