Fatal Error in LiteSpeed Cache – setcookie() “path” issue

I’m experiencing a fatal error with LiteSpeed Cache when submitting a comment. It appears to be related to the setcookie() function and an invalid “path” parameter. Here’s the error message:

Fatal error: Uncaught ValueError: setcookie(): "path" option cannot contain ",", ";", " ", "\t", "\r", "\n", "\013", or "\014" in /home/srv77158/domains/bezschematu.pl/public_html/wp-content/plugins/litespeed-cache/src/vary.cls.php:757

The error is pointing to this part of the code in vary.cls.php:

private function _cookie($val = false, $expire = false, $path = false)
{
    if (!$val) {
        $expire = 1;
    }

    /**
     * Add HTTPS bypass in case clients use both HTTP and HTTPS version of site
     * @since 1.7
     */
    $is_ssl = $this->conf(Base::O_UTIL_NO_HTTPS_VARY) ? false : is_ssl();

    setcookie(self::$_vary_name, $val, $expire, $path ?: COOKIEPATH, COOKIE_DOMAIN, $is_ssl, true);
}

It looks like the path parameter passed to setcookie() contains an invalid character. The error occurs when a comment is posted.

Has anyone encountered this issue before? Is there a recommended fix for this?
