Errors at top of arcade.php

I just install this on my 4.1.11 forum last night and I'm getting these errors at the top of the screen when I go to arcade.php.

"Deprecated: Assigning the return value of new by reference is deprecated in /home/content/17/9197117/html/arcade.php on line 3191

Deprecated: Assigning the return value of new by reference is deprecated in /home/content/17/9197117/html/arcade.php on line 4084

Warning: Cannot modify header information - headers already sent by (output started at [path]/arcade.php:3191) in [path]/arcade.php on line 97"

I've performed all of the recommended fixes but none have had any affect on these errors.

Any suggestions?
