Good afternoon,
I've just decided to make the jump to COPS after using the Calibre content server for about a year. My setup is : Abyss Web server 1x running PHP 5.6. I had PHP up and running, installed COPS but all I get is a blank screen where the catalog should be

. A check of the source from the COPS index.php shows this error
Notice Undefined index: QUERY_STRING in C:\Abyss Web Server\htdocs\index.php on line 67 getJSON.php?complete=1";
I haven't set up a PHP server in a long time and my memory of configuration errors is fuzzy at best.
