 * Is it fixed now or do you get the same message from a different location?
 * BTW: This is not related to PHP 8, but to the server configuration.
    What else
   did you do besides upgrading PHP version?

 * Thanks for following up.
 * I limited messages, so had to wait for the job to run again with that site when
   it would send me a message.
 * Looks like same thing on line 20 and 125 now.
 *     ```wp-block-code
       Warning: Undefined array key "REMOTE_ADDR" in /wp-content/plugins/wp-photo-album-plus/wppa-users.php on line 125
       PHP Warning:  Undefined array key "REMOTE_ADDR" in /wp-content/plugins/wp-photo-album-plus/wppa-wpdb-insert.php on line 20
       ```

   as described here: [https://wppa.nl/docs-by-subject/development-version/](https://wppa.nl/docs-by-subject/development-version/)
   This is a pre-release of the next version. It should fix your issue.
 * The fact that `$_SERVER('REMOTE_ADDR')` does not hold the visitors ip address
   is rather unusual, and is not related to php ver 8 as such, so i would like you
   to do a small test for me:
 * Temporarely activate the (classic) widget **WPPA+ Stats** and tick at least the
   box: **Show IP address**, and tell me if it displayes your ip address or that
   it says **n.a.**

 * I just updated to the latest public version and it looks like the issue is resolved!
   Thank you!
