Prestashop redirects to old domain after changing it in Database

Question

I am trying to create a copy of a prestashop 1.6 e-shop for development purposes from domain.com to dev.domain.com

The process I followed is

1. Disable cache

Answer 1

Your procedure is right, there is only a few factors that may cause your issue

1. Make sure that there is no manual redirection in your web server configuration (or old .htaccess for Apache)
2. Change Prestashop domains from the database (detailed below)
3. Clear all your cache Update Prestashop domains from the database (detailed below)
4. Always test with a browser in incognito/developer mode, disabling all cached redirections. I personally use an incognito Chrome window, in developer mode
5. When debugging, it is a good idea to inspect the logs from your webserver as well as the network exchanges from your browser to identify the source of the issue

Here are a few rudimentary scripts I use to automate the cache cleanup and domain change for Prestashop 1.7.

1. Change Prestashop's domain

Use a template file to generate a .sql file to patch the database. If more convenient, you can manually run that on your database directly.

patch-domain.sql.template:

UPDATE ps_configuration SET value='${SHOP_DOMAIN}' WHERE name='PS_SHOP_DOMAIN';
UPDATE ps_configuration SET value='${SHOP_DOMAIN}' WHERE name='PS_SHOP_DOMAIN_SSL';
UPDATE ps_shop_url SET domain='${SHOP_DOMAIN}', domain_ssl='${SHOP_DOMAIN}';

Generate the real .sql patch file, and apply it

$ export SHOP_DOMAIN=mydomain.com
$ envsubst < patch-domain.sql.template > patch-domain.sql
$ mysql -u  -p  < patch-domain.sql

2. Clear Prestashop cache

Remove all cache files except index.php

clear-cache.sh:

#!/bin/bash
base_dir='./shared/prestashop/html'

# Clear class index in case any override changed
rm ${base_dir}/cache/class_index.php

declare -a cache_dirs=(
    "cache/smarty/compile"
    "cache/smarty/cache"
    "cache/cachefs"
    "img/tmp" # You might want to keep tmp images
    "themes/*/cache"
    "var/cache")

# Clear all cache folder, ignoring 'index.php'
for dir in "${cache_dirs[@]}"
do
    echo Cleaning ${base_dir}/${dir}...
    find ${base_dir}/${dir} -type f ! -name index.php -delete
done
