Fonts load from the old staging site and fail
19 of 23 pages · all sizes
The pages request their Inter, Inter Tight and Open Sans font files from yellow-rat-843239.hostingersite.com, the Hostinger staging address, instead of premiumdataappend.com. Those requests fail, so browsers fall back to other fonts, and the staging address is visible to anyone who inspects the page.
In Elementor go to Tools, then Replace URL, and replace the staging address with https://premiumdataappend.com. Then regenerate CSS and files and clear the cache.
