Question

我在这里呆了一天。我尝试了所有可能的解决方案，但无法解决问题。我收到的错误是：

“警告：session_start（）：无法发送会话cookie-标头已发送者（输出始于 /storage/ssd2/309/8480309/public_html/index.php:22）在 /storage/ssd2/309/8480309/public_html/index.php，第24行警告： session_start（）：无法发送会话缓存限制器-标头已经已发送（输出始于 /storage/ssd2/309/8480309/public_html/index.php:22）在 /storage/ssd2/309/8480309/public_html/index.php，第24行“

我正在尝试将其托管在000webhost上。此警告正在显示。
