I have managed to install the akeeba backup fix you posted a few minutes ago. However I still appear to have problems logging in to the admin page.
I have subsequently renamed the administrator/modules/mod_akadmin by appending _001 to it. This allows me to login to the admin end but clicking on the update button in akeeba invokes a new error message http://mywebsite.com/administrator/index.php?option=com_akeeba&view=liveupdate now says:
403 - An error has occurred.

What do I do?
