Something went wrong, and I don't know what. I followed all instructions exactly. I wiped the new server clean, reinstalled the base ZenCart installation. Created a new MySql. Went through the installation procedure, and everything was working right. Then I uploaded the saved files from the old site, except for the two configure.php files. I modified them with the new MySql information, and uploaded those last. Now the site has vanished again, to be replaced with a 403 error message.

What did I do wrong??
