due to some filesystems nature ( proemintantly VIP ),
require_once was trying to load a directory
I'm not sure why $abs_path was a directory,
albeit from seeing in the code, the redux autoload class puts $abs_path as /uploads/ + /redux/version , so it might start from there,
while this is a temporary fix for wp-admin not to break in some instances, i'm not sure if other issues are present in the plugin.
