Hi Vincent R,
First, thank you for your purchase.
You can't translate the lorada theme with editing lorada.pot file.
You need to make the po amd mo file from lorada.pot file. You can translate the theme easily with translator plugin.
We highly recommended the "loco translate" plugin.
Plugin URL: https://wordpress.org/plugins/loco-translate/
Quick Guide: https://localise.biz/wordpress/plugin/beginners
This plugin will generate the po and mo file with the lorada.pot file. You can translate the lorada theme text easily.
And some texts such as widget titles are added on wp admin panel directly.
So please translate these texts on admin panel directly.
If you have any other questions, please let us know again without hesitation.
Best Regards, C-Themes
