Upgrading Drupal

1. I have updated drupal core to its latest version

2. After updated, I have run "update.php" with the following ERROR message:

>update.php

VERIFY REQUIREMENTS

I upgraded the Drupal 6.18 to Druapl LTS( 6.43) . There were no PHP errors earlier but I now see plenty of these errors in the log. Although site seems to be running fine. What to do?

My VPS: Ubuntu 14, PHP 5.59  :

Non-static method view::load() should not be called statically in www.example.com/public/sites/all/modules/views-6.x-2.12/views/views.module on line 906.

Ran the upgrade from 8.5.1 to 8.53 on a site with SSL protection -- but no content -- seeming with success

However the following errors were indicated:

I've gone through the LTS announcement etc. But what is the systematic way to upgrade to the LTS version?

For example can I just upgrade to this LTS version : https://github.com/d6lts/drupal in normal way?

Hi All,

Just thought I'd share a drupal-core update script I've written for 7.x.  Might save somebody lots of time - it's saving me an age since I wrote it after the most recent release.

Notes:

Hello, I inherited a Drupal site and performed a Database and Module update but not a core update, after making a backup of the site DB and Files.

We are running version 7.52. We have a custom registration page which is now missing some elements. I am considering restoring from the backup but any advice regarding resolving this issue perhaps without doing so would be welcome.
