Plugin breaks chart and admin after update

I’ve seen this issue a couple of times, on multiple websites.

Every now and then when there are update available (be it the plugin or wordpress itself) Analyticator seems to break things.

The chart on the dashboard remains empty (keeps loading)
The widget settings page won’t load anymnore because of an error in the analyticator widgets. this also cause problems when trying to change header images etc.

The only way to fix is is to reset and re-authenticate the plugin and it works again.
But it’s only a matter of time before another update breaks it again.

I manage a lot of websites, so i cannot check all sites on a daily basis and a lot of updates are automated.

Please fix this issue.
It seems that i’m not the only one with this problem, i causes a lot of headaches,
and the issue persists after multiple updates of this plugin.

I really hope for a solution because i love this plugin.
