Drupal 7 core update
A small note, as a reminder for yourself, how to update the Drupal 7 core to the new version.
After creating a backup (recommended), download the archive with the new version. Unpack to a folder. You can immediately delete all .txt files, the .htaccess file and the sites folder from there.
Next, we upload everything that remains to our folder with Drupal 7 installed with a replacement.
After copying is complete, go to https://yourdomain/update.php, where we start the update process.
When the update is completed, go to Reports \ Status Report, where we will see that the version of Drupal should be the same one that we downloaded for replacement.
