 * Hi
 * In my Servers error-log, there is a lot of php warnings like this:
    [Sun May 
   01 12:16:16.147570 2022] [proxy_fcgi:error] [pid 3977388:tid 140461212890880][
   client xxx.xxx.xxx.xxx:xxxxx] AH01071: Got error ‘PHP message: PHP Warning: Undefined
   array key “HTTP_REFERER” in /var/www/vhosts/xxxx/xxxx/xxxx/wp-content/plugins/
   simple-local-avatars/includes/class-simple-local-avatars.php on line 83’
 * Is this something which has to be fixed? Should I be worried about this?
 * php-version: 8.1.3

 * It’s just a PHP Notice, not to worry. Should be a simple change for the developers:
   [https://github.com/10up/simple-local-avatars/blob/develop/includes/class-simple-local-avatars.php#L83=](https://github.com/10up/simple-local-avatars/blob/develop/includes/class-simple-local-avatars.php#L83=)
   to wrap $_SERVER in an `isset` or `!emmpty`.
