Upgrading Drupal

I ran the Drupal 8 migrate function on my Drupal 6 database. It completed successfully. All the nodes appear to be there in the new Drupal 8 site. However...

None of the text is displayed. Only the titles. This occurs on all pages, regardless of type. The front page itself has no text other than the title.

I can edit a node and see the text from the Drupal 6 site there, available for editing. But when I save it, it still does not display.

I can add a new node with "Testing new site..." or some such in the body text. THAT does get displayed after saving.

Question is pretty much in the title :)

Hi all,
I've upgraded a Drupal8 site from core 8.3.5 to 8.3.6 with the command "composer update drupal/core --with-dependencies".

The procedure stopped with the command "Generating autoload files" so I don't think that the system has been upgraded.
But if execute again the command it say that the system is updated.
The backend, in fact, says that the old core is still installed.

So now I don't know which is the core installed and how to have a clean core 8.3.6 not 8.4.0 installed.
How can I solve this problem?

Thank you very much

Hello! I had a problem with updating v7.54 to v7.56 (again apparently) saying there are no database updates of some sort when I go to update.php. Having encountered the same problem twice now, I decided to backup my files and work on it on a WAMP localhost and just reupload the site afterwards. However, when I asked my webmaster to upload the mysqldump I provided him it seems that the version is still stuck at v7.54. There are also modules and themes that were not recognized even though all the files are there in the FTP server.

Just joined Drupal.org. I could use some advice/suggestions. Here's my story...

My wife has a Drupal 6 website that I built for her back in 2011. She has used it consistently over the years since then, but Drupal was never updated. I came down with serious health problems that made that out of the question, and she had neither the time nor skills to do it herself.

Hi so I have read the documents Drupal 7 to 8 but I have questions and errors about migrating from Drupal 7 to 8. So here are the steps I take to try and migrate, maybe someone can help spot where I go wrong:
