Wordpress, the first visit to the abracadabra page, the second one is normal.?

Question

Database

Recently, visitors began to complain.
I couldn't see it myself, the browser's cache gave a normal picture.
I went from the phone - oops, I see abracadabra. Refreshing the page - and everything is OK, regular work.
Any thoughts what it could be? db plugin?

Any thoughts what it could be?

This is archiving (compression). Looks like the server gives a crooked / broken archive, and the browser cannot unpack it.
