I'm trying to install OpenCart 2.1 using the Wamp server but I got this message error.

Warning: require_once(d:\wamp\www\opencart\upload\config.php) [function.require-once]: failed to open stream: Permission denied in d:\wamp\www\opencart\upload\index.php on line 9

CodePudding user response：

Check-in (d:\wamp\www\opencart\upload\config.php) that "config.php" file is still there or not. If it is not, you search "config-dist.php" and "admin/config-dist.php" and rename this "config.php". If there are not then you have to reinstall opencart. Probably it will be OK.
