today duplicate one zencart site, long time not touch the osc solution.
below is something for memo,
– configure file in /root/include/configure.php to set up database and basic info for front end
– configure.php flle in root/admin/include/configure.php to setup admin db connect and details
– if duplicate not working in back end login, after remove all session in DB and cache in files, still not working, my solution is : download version same zc_install folder, reinstall the Zencart, reinstall the database, update the configure of both front end and admin, the site should be working.
zen cart is pretty fast
