php 5.6.38
wordpress 4.9.8
WP Cerber Security, Antispam & Malware Scan 7.7

Gioni I am using WP Cerber Security & Antispam Version 6.7.5 and W3 Total Cache Version 0.9.7

I have been getting error like one below for past 5 months.

18:27:30 UTC] PHP Warning: Cannot modify header information – headers already sent by (output started at /home/wordpresssite/public_html/wp-content/plugins/w3-total-cache/PgCache_ContentGrabber.php:354) in /home/wordpresssite/public_html/wp-content/plugins/wp-cerber/cerber-load.php on line 745

Plugin is updated.

Errors are still showing:

I reached the same conclusion you noted as I reviewed our data in more detail.
