Hello, I am struggling to migrate a Drupal 7 website to Drupal 8, without drush. I have followed the official guide: https://www.drupal.org/upgrade/migrate
The "update" process works properly until it reaches 100%, after suddenly the page becomes white with this error: "The website encountered an unexpected error. Please try again later.", and the website is ko.
I tried 4 different times also disabling every "no core" modules. No results.
Some ideas?
Thanks

You should look in the server
You should look in the server error log to find out what went wrong.
You should also have drush installed even if you are not using it for migration, to help you out, for example by rebuilding caches. Often that fixes things.

Thank you for your answer.
I checked the server error and I have these:

Any help?
Thanks
2006 MySQL server has gone
Whatever other problems you may have, this the first to fix. The mysql server has either timed out, or has crashed completely. Assuming you are trying to run the migration on a laptop / desktop, you could try increasing the timeouts and max_allowed_packet settings. It is of course also possible that your server or laptop is simply running out of resources (e.g. RAM).

Dear John_B, thank you so
Dear John_B, thank you so much for your tips.
The problem was the size of: innodb_log_file_size (my.ini, XAMPP).
Now the migration is completed but I have 2 issues.
Every block in the page is perfect (position and text) but:
1- every node migrated doesn't show the text in the body. I have the title, the date, the author but not the text. I checked the "node__body table" and every records has the right HTML code for every page.
2- Urls alias are set correctly for every node migrated, but they give me "page not found", I have to use the path with the node number.
Thank you so much!
On point 1, note that node
On point 1, note that node body text can go missing if the revision ID in the node body table `field_body` does not match a current node revision in the field_body_revision table. Just a suggestion of something to look for.
As for why the URL aliases do not work, no idea. The first thing I would do is check that they work when you create a new node.

Dear John_B, thank you so
Dear John_B, thank you so much for your help.
Both my issues came from the langcode (italian), now I fixed them and everything works good!
