Nevermind! Solved it.
I accidentally had the code in functions.php AS WELL as having it in bp-custom.php

Sorry!

I used this and attempted to register.
The result was a Internal 500 HTTP Error.

Manually disabled all the plugins and when i attempted to re-enable BP
I got this error:

Plugin could not be activated because it triggered a fatal error.

Fatal error: Cannot redeclare my_disable_bp_registration() (previously declared in /public_html/wp-content/themes/detube/functions.php:35) in /public_html/wp-content/plugins/bp-custom.php on line 8

I believe there is an issue when attempting to activate an account via e-mail that the fix does not cover up.
