By default, phpListings uses '/admin' as the administrator panel directory. As of phpListings 1.0.5, this directory can be changed (renamed) for security reasons or if the same directory name is already in use by third party hosting panel software that overrides your phpListings administrator panel.
You can update your phpListings administrator panel directory by changing the 'admin_directory' setting of the /app/Config/App.php script:
'admin_directory' => 'admin',
Please note that only numbers and English letters can be used in the directory name, spaces or special symbols are not allowed.
