Moodle will be upgraded to version 2.4 on Thursday 25th July.
On the day of the upgrade, Moodle will be placed in read-only mode starting from 9 am. We expect the process to take just over a day to complete.
Moodle will still be usable (read-only) throughout most of the day. This means that during this time you will still be able to access your modules and download files. However you will not be able to submit or mark assignments, add files or update enrolments.
