Description of my issue:
The issue is that the automatic backup starts when I go to do the update to Joomla 3.5. This is despite the plug-in System - Akeeba Backup Update Check being disabled. This site uses Akeeba Backup 4.6.1. On other sites which use Akeeba 4.5.5 this doesn't happen with System - Akeeba Backup Update Check being disabled. This wouldn't be an issue as such but after the backup it fails to update Joomla to 3.5 . It just sits there showing a message updating your Joomla files please wait and nothing happens.
Cheers
