Hi,

I did a fresh Installation of Drupal 8.6.3 on someones site hosted at 1&1.

For some reason if I go to either Users, Modules or Cron it gives me an error page telling me an unexpected error had occured.
I can set Themes or the settings but these 3 only give me a blank page with that error.

Any Idea what might be the reason?

Hi,

We 've got a drupal site showing off some annual report, about the activity of a hospital.  For now the report are in the form of text, where we can found many numbers.

Now we want to put some sexy DataViz into this ! https://en.wikipedia.org/wiki/Data_visualization

If it's such a good idea to have nested docroot, for example a `web` subdirectory, and to have contrib modules in `modules/contrib` and custom modules in `modules/custom`, why doesn't the Drupal 8 installer set that up from the outset?

Hi guys,

I'm starting to build my first site with Drupal8.

When I transfer the folder remotely via FTP, use transmit, it always happens that the file transfer speed slows down and the transfer always ends with 4/5 files not transmitted correctly.

Is it a problem or does it happen to other users?

With Drupal 7 is all OK.

Thanks.
