Dates are showing incorrectly

I am developing the following site: http://www.adbalarms.co.uk and the testimonials are all showing the dates as WedWed,NovNov,20162016 and not the dates set on each testimonial. In the dashboard all seems fine, but the front end is showing these incorrect dates. Please let me know how to fix it or if it is a mistake I have made in the settings.

I have uninstalled and re-installed the plugin files manually using the FTP with no success.

Thanks.
