Fatal error: Cannot re-assign auto-global variable _GET

I get this error:

Fatal error: Cannot re-assign auto-global variable _GET in wp-content/plugins/vr-frases/includes/vr-frases-functions.php on line 32

This is actually not a wordpress version problem per se. It seems to be related to PHP, the plugin should not be passing $_GET in as a param into a param named $_GET.

If you modify the following file, it solves this error:
