[abdoart]

I have a premlem i want to install 2 prestashop 1.7 stores but on the same domain the problem is i want to copy the old store on the new one and my urls of the store will be like this

mystore.com/myoldstore
mystore.com/mynewstore

what i did is i copied the old folder in the new one and also the database and i change the database configuration

but when i go to my new store

mystore.com/mynewstore

it keep redirecting me to the old store mystore.com/myoldstore

try opening in chrome incognito window, also .htaccess will be read from root (mystore) so make sure rename it if it exists ._httaccess, hope that helps
