I've got the same issue trying to install a prestashop site in local (working on prestashop 1.7.4.4).
I've modified domain and domain_ssl in ps_configuration and ps_shop_url as well as deactivating friendly urls
After all that I cleared the cache. I also deleted .htaccess and remade robots.txt
The strange thing is I can access the backoffice on localhost but the website itself redirect me to the web...
