For an unknown reason, new users currently cannot login to their accounts and instead are presented with a blank screen. This is currently being fixed. This is the second of a two-fold issue with the registration system which, due to a bug in the system design, was not saving user passwords. This has already been fixed
Another post will be made when the issue is resolved and affected users will be issued a 'default' password which they will be advised to change.
Sorry for an inconvenience caused.
