Jag får följande fel när jag försöker logga in på min sida. Det fungerar när jag kör den lokalt och det fungerar i firefox men inte i Internet explorer. Det har fungerat men slutade att fungera i helgen, jag har inte gjort några ändringar i koden.

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Någon som vet vad som kan vara fel? Kan det vara något på webhotellet som ändrats?

Jag använder den här koden vid inloggningen
<code>
Public Shared Function Encrypt(ByVal cleanString As String) As String
Dim clearBytes As [Byte]()
clearBytes = New UnicodeEncoding().GetBytes(cleanString)
Dim hashedBytes As [Byte]() = CType(CryptoConfig.CreateFromName("MD5"), HashAlgorithm).ComputeHash(clearBytes)
Dim hashedText As String = BitConverter.ToString(hashedBytes)
Return hashedText
End Function
