First, we can change the product info summary positions as you want.
But to do this, we need to modify PHP code via our developers. Because we don't know well about PHP language.
If you can pay some extra budget, we will contact our developers and try to help you.
And next, you mean you want to change the website language with your local language?
To do that, you need to install Wordpress translator plugin and translate lorada theme folder and lorada-core plugin folder.
Then, you can translate your website.
We recommend the Loco translator plugin.
If you have any other questions, let us know again.
Best Regards, C-Themes
