Hello,
Thanks for contacting us.
Edit content of custom pages, like Home, using Elementor. Strings of default WC pages, like My account, Cart, can be found in translation files of the theme, WooCommers and XStore Core plugin. Go to Elementor > Settings > enable editor for static blocks and products, then you will be able to edit Footer static block using Elementor. Some texts from the header you need to change via Theme Options > Header Builder.
Let us know if you need any further assistance.
Regards
