I get these errors all day when using google analytics or WP stats plugin. It also has killed my RSS feed and is slowing down traffic.
First this plugin ruined our SEO...now its killing us slowly from within. Please...test your product before you release it.
FYI: I informed the plugin developer about this defect two months ago. Both in a thread here and on Facebook. Nothing has been done. Deactivating this plugin.
