[Plugin: Welcome Visitor] Plugin won't activate

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

Fatal error: Cannot redeclare getHostname() in /[removed]/wp-content/plugins/welcome-visitors/welcome_visitor.php on line 114

I’ve removed the full filename from the above error for security reasons.

David.
