Problem starting xampp after reinstall

[harkon]

I just installed the newest version of XAMPP in order to move to the newest version of PHP, 7.something, but when I navigate to http://localhost/xampp/ and enter the username and password, I get this error:

Server error!

The server encountered an internal error and was unable to complete your request. Either the server is overloaded or there was an error in a CGI script.

If you think this is a server error, please contact the webmaster.

The Apache and MySQL modules in the control panel seems to be working. What could be the problem?

/xampp/ subfolder does not contain any functional files in the current Xampp versions.

http://localhost/dashboard/ is the new default page.

Thank you. The new URL opens but when I try to access phpMyAdmin, MySQL returns an error in Bulgarian, saying that the connection cannot be established because of invalid configuration, that phpMyAdmin cannot connect to the MySQL server, and that I should make changes to the config.inc.php file.

What should I do about it?

The error I get is as follows:

phpMyAdmin tried to connect to the MySQL server, and the server rejected the connection. You should check the host, username and password in your configuration and make sure that they correspond to the information given by the administrator of the MySQL server.

Where should I make changes?

The problem is solved. I had to manually add password to the file config.inc.php on the following line:

$cfg['Servers'][$i]['password'] = 'mypassword';
