I am happy to disable to cache since this site is a copy of the real site. However, I just logged in to disable to cache and it does appear that all of the caching is already disabled. That is what I try to do when I create a replica of a site for troubleshooting.

System -> Global Configuration -> System Cache is disabled.
Extensions -> Plugins -> System - Page Cache is disabled.
Extensions -> Plugins -> System - Regular Labs - CDN for Joomla! is disabled.
Can you think of any other cache that could be enabled?
Thank you so much, Sean Carney
