I re-uploaded the files and reinstalled the product.
Now it works.

What is the table name of the stored items?
I found only itemstats_cache but there are no entries.

I created the table wowitemstats manually:

CREATE TABLE wowitemstats (
item_name varchar(100) NOT NULL default '',
item_id varchar(100) default '0',
item_color varchar(20) NOT NULL default '',
UNIQUE KEY item_name (item_name) );

Hope this will help to cache the items.
