hi

I installed a fresh magento 2 store version 2.2.3

new database

deleted all old files

unziped the package and installed magento

for some reason when i look at 

/var/log/debug.log

text/x-log debug.log
ASCII text, with very long lines

[2018-05-11 03:39:57] main.DEBUG: cache_invalidate: {"method":"POST","url":"http://www.hijabgem.com/setup/index.php/install/start","invalidateInfo":{"tags":["BACKEND_MAINMENU"],"mode":"matchingTag"}} []

this is a tiny snippet of what it going onn, theres even bits looking for old template files

why is this happening, how do i stop it?

i flushed the cache and switched of super cache before installing, i don't understand

Kind regards
