Topic: Metadata problem with "Woo Detail Product Page Builder"

Yes i am using this plugin to build my single product pages structure.
The plugin developer wrote me that the problem with the used theme.
If i turn off the “legenda” theme then the plugin works fine.
What can i do in this case?
What have you changed in the product metadata?
Why can’t i use is with my plugin?
And why works fine with any wp basic theme?
Thank you for your cooperation.

Aha…
And what can i do? There are a lot of plugin in the world.
And i would like to use many-many woocommerce plugin.
But can’t i use them in the ‘legends”a theme?
I bought this theme because i liked it. But now i don’t know what i can do.
The custom product structure is very important to me.
And i think it is a very simple thing to solve for you.
Any idea?
I try it with a shortcode plugin “Shortcodes Ultimate” and paste the product meta key data.
But i don’t know what is the meta key of product. 🙁
Maybe can you help me in this?
What is the meta key of product?

And other meta question:
What is the breadcrumb meta key?
I would like to place it some place on my pages too.
Thanks,Attila
