Lost my Custom CSS

[alliima]

I updated WordPress and the Lay Theme through Hostinger because I was unable to update Lay Theme through the WordPress dashboard.

After updating, I lost the custom CSS that was applied to the homepage of my website. My homepage is set up as a “category” page, so I’m not sure if that has anything to do with it.

I downloaded a backup through Hostinger, but I can’t seem to find the specific CSS file in the backup. Maybe I’m looking in the wrong place.

I’d rather not restore the entire website to the previous version because I’ve made some changes since the backup was created.

Is there any way to recover the missing custom CSS from the backup, or is there somewhere else I should look?
