HTTP ERROR 500

[dx6]

I can go to my main directory but when I got to /admin it just says "HTTP ERROR 500" 

How do I fix?

With error 500 you need to switch on development mode to see what is the error.

Edit the file i.e. controllers/admin/AdminDashboardController.php & replace this

parent::setMedia();

with 

parent::setMedia(false);

SImplexml_load_string error is due to unavailability of  php-xml extension. Have you restarted the apache server after installing the extension?

To fix this issue,

Change this

public function setMedia()
{
        parent::setMedia();

to

public function setMedia($isNewTheme = false)
    {
        parent::setMedia($isNewTheme);
