Page loads incorrectly when plugin is active

There are four widgets on the home screen, everything shows correctly when the plugin is deactivated. If I activate the plugin and login to the site, the content within the widgets is no longer correct. Instead of widget1:content1, widget2:content2, widget3:content3 and widget4:content4, it shows up as widget1:content2, widget2: content2, widget3:content3, and widget4:content4. How do I resolve this so that it loads correctly immediately after entering the password?

Thanks!
