    Recently there has been an increase of these errors in the log files.

    [Mon Aug 01 10:37:01.375805 2022] [php:warn] [pid 17241] [client 152.32.131.196:12882] PHP Warning: Undefined array key “HTTP_USER_AGENT” in site name.com/wp-content/plugins/participants-database/participants-database.php on line 2937

    Any idea of what is causing that?

    This is happening because your web server does not include the HTTP_USER_AGENT item in the $_SERVER array. It’s a little unusual (which is why I hadn’t anticipated this), but not much of an issue and can be safely ignored.

    Thank you for taking time to explain. It’s happening due to some script attacks from bad actors/bots. We were having issues with the reCaptha plugin content security headers, and some script monkeys were able to force through registration. They are now blocked – but still trying to access the PDB login link.
