We have a large website that uses a mix of pages in WP Page Builder and Elementor.
The website is in Hebrew, and we need to add WPML to it, so that we have the ability to translate it into English.
Some of the pages in the site are custom built, but mostly it's very simple.
The theme that we use is X, and we have implemented a child theme to make it more flexible.
That's about it :)
