After upgrade, api can't get latest data after the upgrade date

hi all, so i just upgrade my piwik to the latest 4 days ago.
Now i have noticed when accessing the data via the API… such as:
http://mydomain/piwik/?module=API&method=Actions.get&token_auth=authcode&idSite=1&period=day&date=last7&format=xml&language=en

everything past the date of the upgrade is empty. just:
<result date="2015-12-02"/>

while everything before the upgrade date is still there.
now if i go into the piwik dashboard and look. all the data is there on and before the upgrade date.
so it’s as if the upgrade someone how stoped the api from access new data.

anyone have any thoughts on how to fix this?
