The only change on my side was to apply am OS X update (running VMWare Fusion, Ubuntu v14)

thank you,

@deanm : By an unknown reason, one (or more) of the checkpoint files ( "*.chkp" ) exists but is empty (zero bytes). Try to locate and remove it ( it should be located at <MINEMELDROOT>/local/data )

[deanm]

Thanks, that worked!

@xhoms I am trying to change name MINEMELD from file view.html located in webui/www/app/login. However, changed name does not reflect on login page. It works when I open html page in browser.

Can you please help?
