For some reason mage 2 is not creating files that seems to be needed for a proper working of the shop. For example there is a file http://dev.domain.co.uk/pub/media/catalog/productno_selection requested but a 404 is delivered because it is not there. I guess that might be a file containing the amount of items in basket since my top right corner does not state the products amount and I can't reach the basket without going directly in there via url. The top right basket doesn't let me in, stating that no products are in basket... which is wrong.
Going to that url directly delivers an empty page.
The other files missing are javascript-files that should be created by mage2 in pub/static too, it seems. For example I mapped the right filename (.js is not needed or allowed) to the left handle
'jquery_191': 'js/jquery-1.9.1.min',
Then mage2 requests the filename http://dev.domain.co.uk/pub/static/frontend/company/celo_theme/de_DE/jquery_191.js but this file does not exist.
Going to that file directly gives some mage bugs claiming that the file does not exist.
What's wrong? Why are these files not created? I think it brings certain problems to my installation.
PS: Errors in chrome console after setup:upgrade and setup:static-cache:deploy with the correct language.
