I see the following in my error log:
PHP Fatal error: GoogleAnalyticsSummary::getVisitsGraph() [<a href='googleanalyticssummary.getvisitsgraph'>googleanalyticssummary.getvisitsgraph</a>]: The script tried to execute a method or access a property of an incomplete object. Please ensure that the class definition "Google_GaData" of the object you are trying to operate on was loaded _before_ unserialize() gets called or provide a __autoload() function to load the class definition in /wp-content/plugins/google-analyticator/google-analytics-summary-widget.php on line 242
Did Google's API change again? This happening for anyone else?
