WordPress Popular Posts Plugin Issues

Hello everybody! I downloaded and activated the ‘WordPress Popular Posts’ plugin and an error occurred. It interrupts my featured post slider on my homepage to where it doesn’t do the actual sliding anymore.

My website is centsmakingsense.

The plugin is deactivated now so that my slider can function correctly but I really love this plugin. It is the best version of this type of plugin I have found. Does anybody know how I can use it and still have my slider working properly?

Thank you in advance for any suggestions.
