I have fixed the problem for the grey links. Find the config.php in your itemstats folder locate this
Code:
define('dbhost', 'localhost');
define('dbname', 'DBNAME');
define('dbuser', 'DBUSER');
define('dbpass', 'DBPASS');
define('item_cache_table', 'item_cache');
and add this
Code:
/*define('dbhost', 'localhost');
define('dbname', 'DBNAME');
define('dbuser', 'DBUSER');
define('dbpass', 'DBPASS');
define('item_cache_table', 'item_cache');*/
You are just commenting that code so it doesn't write over another php file that has your DBs username and password info in it.
It worked for me and I hope it works for others too!
