Why does google give 200 and in the browser 404?

Question

PHP

I don't know where to dig. Google web master gives 200 to a non-existent page, but in the browser 404. I disabled all plugins, the Word press updated.
traktor.adr.com.ua/abracadabra (in the browser 404), Google bot sees it as 200.

Answer 1

The problem in the plugin was "estore". Botam returned 200 status.

Answer 2

curl -v -A 'Mozilla/5.0 (compatible; Googlebot/2.1; +http://www.google.com/bot.html)' http://traktor.adr.com.ua/abracadabra
