Installing Drupal

Hello,
I just tried to install Drupal 8.3.6 the first time.
Alter entering the database I got this error:

Fatal error: Interface 'Drupal\locale\StringStorageInterface' not found in /home/xy210hob/www/home/core/modules/locale/src/StringDatabaseStorage.php on line 10

In the code of "StringDatabaseStorage.php" there is the line:
"use Drupal\Core\Database\Connection;"

On my Server I there is no Directory "Core\Database".

I would be glad if someone can help me

Just a note to anyone installing Drupal to check the following list of PHP settings and ensure that they are all correct before installing Drupal:

https://www.drupal.org/docs/7/system-requirements/php#shortlist

After installing Drupal, many of the settings listed above can be verified directly from the admin status report page which includes a link to view PHP settings right on it.

Hi,
after installation of drupal-8.3.4,
when I try to access the menu items of installed drupal-8.3.4 it is showing error404, but the home page is loaded perfectly
I am not able to understand Where the problem is, my guess is due to some permissions.
Plz guide me

ThankU,

I noticed that sometimes when installing a new module that the installation, when underway, stalls and does not install but if I repeat the process several times, then the installation succeeds. I do not know if this due to module packaging, internet provider, computer or website host, etc. I just thought I would mention it in case others experience this also.
