Well, easy to reproduce (https://3v4l.org/3JEbK), but impossible to fix without some information. What is the actual code that is causing this error?

[niyonx]

In the aws-sdk package,

  public function __construct($enabled, $host, $port, $clientId = '')
    {
        $this->host = $host;
        $this->port = filter_var($port, FILTER_VALIDATE_INT);
        if ($this->port === false) {
            throw new \InvalidArgumentException(
                "CSM 'port' value must be an integer!");
        }

        // Unparsable $enabled flag errors on the side of disabling CSM
        $this->enabled = filter_var($enabled, FILTER_VALIDATE_BOOLEAN);
        $this->clientId = trim($clientId);
    }

In the jet-tabs plugin,

$is_item_active = filter_var( $item['item_active'], FILTER_VALIDATE_BOOLEAN );

seems like it has to do with the FILTER_VALIDATE_BOOLEAN

[cmb69]

Thank you! FILTER_VALIDATE_BOOLEAN should equal to 258, so apparently there is something strange happening there. Do you have OPcache enabled? Is the problem "fixed" after you reset OPcache (if in doubt, re-start the Webserver and/or FPM process)? Do you have JIT enabled?

[niyonx]

Yes, the problem was fixed when I restarted the fpm process.

No I don't have opcache or jit enabled. They were all commented in the php.ini. Do you recommend I enable opcache?
