@Jeffrey Drumm 
I have tried as per your suggestion but still can not login I believe changing the password here is the same as changing the pass in the management portal SystemAdministration -->configuration -->security -->users and I have read here my understanding is that the two are separate please correct me if I am wrong but I keep on coming to the same page after using the terminal ^SECURITY and restarted IRIS

@Stuart Byrne 
I am currently experience the same problem was wondering how you got this solved please

@Enrico Parisi 
I am sure not sure what the whole error is about but the Constructor key word says it all
