Translated pages showing blank

We use one domain per language and I managed to set up everything correctly. But I am having issue with showing content that is translated. I only get blank content where header and footer shows.

Site is using elementor, but I tried switching to gutenberg without results. I changed theme and removed all plugins except elementor and woocommerce and still had the same issue.

Furthermore the blog page is also not translated, as it shows a blank page there as well.

The page I need help with: [log in to see the link]
