Undefined index: HTTP_REFERER When Creating New Blog

When I create a new website and click the activation link in the email, I am taken to http://mydomain.com/wp-activate.php?key=96d1062337f9dde9 and it says my new blog is successfully activated but I get an anti-splog stack trace:

Notice: Undefined index: HTTP_REFERER in C:\inetpub\woyal.com\wp-content\plugins\anti-splog\anti-splog.php on line 680

It looks like this line is the culprit:
$api_data['activate_user_referer'] = $_SERVER['HTTP_REFERER'];

Is there something wrong with the plugin?

    Hey there @adam_fisher,

    Hope you're well! :slight_smile:

    Thank you for your question however I did not receive the same error you got when I tried this. Could you tell me the url in question? I want to register myself also try deactivating all plugins as it maybe a conflict issue.

    Looking forward for your reply! :slight_smile:

    Best Regards,

    P.S I noticed that you are using older version so I suggest you update them to the latest one.

    My site is not public yet. The error happens when I click the activation link in the email (link mentioned in original question). Here is the stack trace:

    Hi @adam_fisher,

    Thanks for your reply and sorry for the long delay.

    I just tried this with my own install but I can't see any problem. Could you upgrade to the latest version and try this again? If still doesn't work and let me know and I will flag a Second-Line Support to look this for you. I also suggest that you follow this manual before we dig deeper: https://premium.wpmudev.org/manuals/using-wpmu-dev/getting-support/

    Have a great day.

    Kind Regards,

Thank NAME, for their help.

Let NAME know exactly why they deserved these points.

Gift a custom amount of points.
