We do apologise if you had a short time when the training system was not working, but we needed to update to the latest version of Moodle. This is version 4 with many additional features. We hope this will bring us extra security, as we have had several spam users, although we may have to introduce Google recaptcha to help keep the site safe. Thank you for using our Moodle training course site and we will keep checking it is maintained, but do let us know if you have any problems.
