Undefined index

Hi,

I see a lot of these warnings in the debug.log.
It started “30-May-2019” and I already have more than 2000 of these warnings up until now.

# grep "Undefined index" ~/www/wp-content/debug.log | grep -m1 "cleantalk.php on line 525"
[30-May-2019 21:43:00 UTC] PHP Notice:  Undefined index:  in /xxx/wp-content/plugins/cleantalk-spam-protect/cleantalk.php on line 525
# grep "Undefined index" ~/www/wp-content/debug.log | grep "cleantalk.php on line 525" | tail -1
[05-Jun-2019 17:54:45 UTC] PHP Notice:  Undefined index:  in /xxx/wp-content/plugins/cleantalk-spam-protect/cleantalk.php on line 525
# grep "Undefined index" ~/www/wp-content/debug.log | grep "cleantalk.php on line 525" | wc -l
2185

The line number regarding this warning has changed with today’s last upgrade of the plugin since it is now referring to line 541 and not 525 anymore.

WordPress 5.2.1
Anti-Spam by CleanTalk 5.120

Could you please investigate on this issue?
Thank you.

Best regards,
Stf.
