I have been manually been doing Drupal 7 and 8 updates on cPanel for many years. I carefully read what files need to be updated and what files need to stay.
Recently, there was an update to PHP 7.4. I cannot anymore manually update using Filezilla. I only get a generic server error, which doesn't say exactly what happened.
Has something changed in Drupal to cause this to happen? I really do not think it is a cPanel's issue.
