Anybody knows what should I do to make this works? Thanks

Hi,

please delete _all_ files at your server and use the MM-Package from german version of website https://now.metamodel.me/de/home

The better way is to use composer...

Thanks man, that's helped. Hope I'll not have any other problems from now.
