Warning: Undefined array key "HTTP_REFERER" in shurly_analytics_shurly_redirect_after(

Hi, I have created the patch for the issue. Please review.

Hi, tested it, thanks!

A wonderful opportunity to learn about null-coalescing operators: https://www.php.net/manual/en/migration70.new-features.php#migration70.n...

Just made a visual check of the #6 patch so I didn't know if this will work:

$dr = $_SERVER['HTTP_REFERER'] ?? : NULL;

The correct form is without ":"

$dr = $_SERVER['HTTP_REFERER'] ?? NULL;

Hi @C-Logemann,

Thanks for pointing this out. I will work and fix this.

Fixed syntax error and generated new patch.
