exactly as Gizmo wrote. expanding on that -
its not so much that the cookie itself was corrupt. but more so that the data inside the cookie was corrupt. such as storing some dashboard data in the cookie file so it does not need to be regenerated at every visit. total users, new users, users last week, etc. the corruption may a ",,,,,," instead of the intended "0,0,0,0" to the cookie file. NULL or EMPTY variables instead of the count of "0"
