Error message

Hi, I’m getting the following messages on my wordpress error log that seem to point to the cleantalk plugin.

I was wondering if there was any setting that needed to be changed on my site. I’m using the current version of wordpress and your plugin on an nginx server

2026/06/30 11:36:51 [error] 940#940: *2716 FastCGI sent in stderr: “PHP message: PHP Warning: http_response_code(): Calling http_response_code() after header(‘HTTP/…’) has no effect in /var/www/20thcenturybox.com/wp-content/plugins/cleantalk-spam-protect/lib/Cleantalk/ApbctWP/Firewall/SFW.php on line 571″ while reading response header from upstream, client: , server: 20thcenturybox.com, request: ” /product/dinky-toys-100-fab-1-rolls-royce-tall-version-blister-bubble-repro-box/ HTTP/1.1″, upstream: “fastcgi://unix:/var/run/php/php8.5-fpm-u6_20cbtest.sock:”, host: “20thcenturybox.com”

Many thanks.
