Upgrading Drupal

Hello Drupal community,

I have a D6 site with like 500 articles I'm trying to upgrade.

I'm getting that error : d6_field_group plugin must define the source_module property

I've tried to apply the patch#7 mentioned here https://www.drupal.org/project/field_group/issues/2951335 (see details below) but still get the error.
Destination site is using Drupal 8.5.4
Field Group 8.x-3.0-beta1
PHP 7.0.30

Hello,

This one has stumped me.  My theme works fine when it's assigned as the "admin theme", so I know the theme itself isn't broken.  However, all other pages show only content.  No header, no menus, no footers, and certainly no theme files.

I switched to Seven and still no theme, menus, etc.  So I don't think it's a theme issue.

Any hints or suggestions? 

Thanks

Hi,

after upgrading the core of Drupal7 site to the version 7.59 and after upgrading other modules I have a "+" character in the output of each page of Drupal. This is the source I can see:

Yesterday I upgraded to drupal 7.59 and after the upgrade my entire custom theme worked except for one section. We have a page inside of our theme that you must select a customer type and then it will serve a form for that specific customer.

Hi,

I am building a new site in Drupal. Once built I want to import the user information from another site into the new site. This will allow users to login and view their information. Initially as a test I just want to migrate user information and roles. I have migrated the following:
