這看起來單純是CSS沒載入
可能要看一下改成https 登入後
css 是不是也有透過https 載入
我剛重讀了HTTPS網頁
會有這樣的讀取錯誤
Mixed Content: The page at 'https://bbs.yeeapps.com/forum.php' was loaded over HTTPS, but requested an insecure stylesheet 'https://bbs.yeeapps.com/data/cache/style_1_forum_index.css?YsR'. This request has been blocked; the content must be served over HTTPS.
看起來CSS是透過HTTP載入
但是HTTPS不容許混合使用
要就全部都用HTTPS
