Errors in log

Hi, your plugin works perfectly fine for me but I just saw that I’m getting heaps of errors like this in the log:

[10-Jun-2021 10:53:24 UTC] PHP Warning: session_start(): Cannot start session when headers already sent in /home/xxxxxxx/public_html/wp/wp-content/plugins/honeypot/wp-armour.php on line 19

Any idea?

Thanks!
