I have a Magento 2.1.5 installation running, but it only works if I change my document root to /pub. If I don't, I get a bunch of 404 errors:

The problem is that eventually I'll have to move the installation to a hosting provider where the document root cannot be changed.
Only a folder called _requirejs is created within the static folder. There's no version1492703026 anywhere to be found:

I've tried the following:
- Modify
di.xmlas per here - (Re)deploy all static content via the command-line
- Rewrite everything to
/pub - Restore the
.htaccessfiles within the web root and/pub
Would anybody have any idea what's going on?
Thanks in advance!
