Upgrading Drupal

Hi!

At the https://www.drupal.org/blog/drupal-8-4-0-rc1 had wrote:
"Some text changes were made since Drupal 8.3.0. Localize.drupal.org automatically offers these new and modified strings for translation. Strings are frozen with the release candidate, so translators can now update translations."

SO, is it normal to have

Trying to update pages in a Drupal 7 website and keep getting an error saying "The website encountered an unexpected error. Please try again later.
". Log files say it has to do with Notice: Undefined index: body in pagination_node_view() (line 260 of /home1/lifestz0/public_html/fnf/sites/all/modules/pagination/pagination.module).
Some peopel say patches. No matter where I look I am getting so confused.

Hi guys,
upgrading a Drupal7 site I can see this warning:

The following module is missing from the file system: variable_advanced. For information about how to fix this, see the documentation page. bootstrap.inc:1143 [warning]
Performed update: pathauto_update_7006

What is the module that is missing?
I can't find a module called "variable_advanced".

Thank you

Claudio

I have a test Drupal 8 site on my local windows 10 PC created with Dev Desktop. It is configured to bug me by email when there are updates and upgrades available. These messages are telling me to upgrade to 8.3.7 immediately.

I am getting this fatal error after upgrading from 8.35 to 8.37 :
"Call to a member function access()" on "core/modules/block/src/BlockAccessControlHandler.php" on line 119
Any ideas ? I don't understand what I can do ?
Many thanks for your help.

I cannot upgrade my site beyond 8.3.4 without generating a ["user_role" entity type does not exist error]

I have attached a PNG of the error message.

When I go back to 8.3.4 the site works fine with no error messages on status page (except that Drupal needs to be upgraded to 8.3.7).

I'm running PHP Version 5.5.38 with a memory limit of 134217728.

I have no undefined field names or field types.

I'm logged in as user 1 and have rebuilt permissions and flushed all caches.

I've had no other problems except not being able to upgrade beyond 8.3.4.
