Hello,

Please post the contents of the .htaccess file in the /products directory. If using cPanel's file manager you'll need to enable the viewing of dotfiles to see it. Also, verify that nothing is CHMOD 777. Generally, files should be 644 and directories 755.

I made a .htaccess file, and it's contents are below:
