mx global causes an error and overall bad UX on website

[larioteo]

Hello,

the option mx global causes an error.
Error:
Invalid option 'MX_GLOBAL'

Also the user experience on the website is rather ..., it looses inputs if an error is raised. I tested it a little bit, selecting debug and mx, -> everything gets lost. Happens also with mx global.
Error:
option MX can not be used together with DEBUG

Maybe the UI should show the user which inputs are valid, before he clicks generate and looses every input.
