Unable to access client area just after registering a new domain

Just after purchasing a new domain on hostafrica.com, I am unable to login to the client area to manage my DNS settings. I was previously using an international provider and was looking forward to trying something local. Unfortunately, I was utterly disappointed with sloppy error messages which show the entire Stack trace of the error? It does not inspire a lot of confidence, and I believe the team can do better, and I hope they do!
