發佈網站後出現錯誤

Question

大家好，我正在管理一個用asp.net mvc4編寫的網站。不過，我對我想發佈的佈局和CSS樣式進行了一些更改，以更新當前網站。發佈之前一切工作正常，當我在發佈的過程中，我確保我沒有觸摸web.config文件，我只檢查了我想更新的文件，這主要是一個Html和CSS的變化。

發佈後，我試圖登錄，我開始一個錯誤說

Error 
An error occurred while processing your request. 

請幫助我。我可以提供其他任何可以幫助我解決此問題的信息。

，當我試圖在一個我對我的本地主機我得到這個錯誤

看到你所得到的錯誤後，這個問題似乎是事實，你叫WebSecurity初始化連接之前。

編輯拋出這樣的錯誤文件：

public ActionResult Login(LoginModel model, string returnUrl) 
{ 
    if (!WebSecurity.Initialized) 
    { 
     WebSecurity.InitializeDatabaseConnection("DefaultConnection", "UserProfile", "UserId", "UserName", autoCreateTables: true); 
    }
