wordpress symlink plugin error

I'm using Wordpress 4.3.1.

As far as I know, until Wordpress 3.9 the Symbolic links were broken; __ FILE __ global variable was returning the wrong path, therefore, functions such as plugin_url() were returning the wrong URL.

Then, it was fixed in WP 3.9, but seemingly, it is still broken on my end.

Any thoughts why?
