htaccess DirectoryIndex cart.php
 

by default, after install v5.1, the htaccess file with following command.

Options -Indexes
DirectoryIndex cart.php
FileETag none


If I did not delete the "DirectoryIndex cart.php", then type blog.xxx.com.my will get access denied.

is there any problems or security issued by remove this statement ?
any other alternative way to do it ?

"DirectoryIndex cart.php" makes the server to load the X-Cart's front controller when a visitor opens your domain - this should not trigger any error unless you have some specific server setup.

What is blog.xxx.com.my? Would you like to install Wordpress to this subdomain, and keep X-Cart installed at xxx.com.my? If so, the server should route these domains into different web directories on the server.

I install my wordpress in Subdomains.

I confirm that, if "DirectoryIndex cart.php" in htaccess is not remove, when I try to access blog.xxx.com.my will get 403 Forbidden error.

Are X-Cart and Wordpress installed into different directories on the server? I guess so.

Is your server configured to route www.* domain to the directory with X-Cart, and blog.* domain to the directory with Wordpress? If so, .htaccess from the X-Cart's directory should not affect the Wordpress installation (so, it may be a server misconfiguration problem).
