But now changed hosted primary domain is [login to view URL] on my server. And then now I can not access prestashop with both domain. hosting settings are all normal. I did below processing but still can not access. ////////////////////////////////////////////// UPDATING YOUR DATABASE Log into cPanel, then go to "PHPMyAdmin" and log into your PrestaShop database. Go to the table "ps_configuration" and locate the records for PS_SHOP_DOMAIN and PS_SHOP_DOMAIN_SSL. Change these to the new domain name. Check the configuration table for any other entries that contain the old domain name and change accordingly. UPDATING YOUR CONFIG SETTINGS Via FTP or the file manager in cPanel, modify the PHP file /config/settings.inc.php. Look for the entry for PS_BASE_URI__ and modify as necessary. For a shop located in the root, it should read: define('__PS_BASE_URI__', '/'); //////////////////////////////////////////////////////////////////////// Some body help me for this job. Please bid.
