400 错误请求 apache ssl

Question

Bad Request
Your browser sent a request that this server could not understand.
Reason: You're speaking plain HTTP to an SSL-enabled server port.
Instead use the HTTPS scheme to access this URL, please.

当通过 https:// 访问时，网站成功打开。但是在 http:// 版本中打开时，会显示 400 bad request 错误。我也重启了apache。

我的 wordpress .htaccess
