I am trying to install jcow 4.3.1 for testing. I am using ubuntu server 17.04 and have installed a "LAMP" and "OPENSSH" server. when I put a index.php file in the html folder it shows the php info. I have uploaded the jcow files to the html folder and it will not work. I have also deleted the html folder and placed the jcow files directly in the www folder and still cannot get the install page to show. any help would be greatly appreciated. thanks
