@justingambit. Thanks for posting. Could you please clarify which version of Easy Folder Listing you are trying to install on Joomla 3.6.5? The current version of Easy Folder Listing, version 3.0.4, is tested to work on Joomla 3.9.x or Joomla 4. You will need to upgrade to Joomla 3.9.13 to have it working properly.
