I am getting the following error message when trying to backup any of the seven courses I have created:
Fatal error: Out of memory (allocated 40108032) (tried to allocate 4864 bytes) in /content/HostingPlus/d/u/durhamscitt.co.uk/web/moodle/lib/portfoliolib.php on line 809

The php page it affects changes most times.

I am trying to backup a course from Course Administration > Backup while logged in as admin user.

The courses themselves contain minimal data at the moment as the site is still being tested and configured.

The memory limit is set to 128MB, this has been verified by myself as well as the shared hosting provider.
