Hi,
I get this error:
If difficulties persist, please contact the website administrator and report the error below.
0 Call to undefined method Joomla\CMS\Application\SiteApplication::isAdmin()
@alindebian. Thanks for posting your issue. Could you verify which version of Easy Folder Listing Pro you have installed?
The isAdmin() function call is only present in the Easy Folder Listing Pro 3.7.x code. If you have Easy Folder Listing Pro 3.7.x installed, please upgrade to Easy Folder Listing Pro 4.1.x.
