For localhost, you can for example (Windows guide):
Install portable XAMPP Version 5.6.3
Create folder in (depends where you install xampp): C:\xampp\htdocs\mywebsite
Extract archive to: C:\xampp\htdocs\mywebsite (Use 7zip, issues are possible with some archivers)
Create empty file: C:\xampp\htdocs\mywebsite\install.txt
Run XAMPP, Apache and MySQL
Databases->Create new “mywebsite” as attached screen
If no then just enter your wanted details and for database:
DBNAME: “mywebsite”
DBUSER: “root”
DBPASSWORD: LEAVE EMPTY
EDIT:
We noticed XAMPP >=8.1.6 causing blank screen issue
quickfix solution:
after you extract zip
edit application\config\production\database.php
this change to false:
