I have just installed a fresh copy of Yii2 advanced and am having trouble getting the style sheets to load. The error seems to be that Yii (or webserver) cannot create path /var/www/frontend/web/assets/1ecfb338/css
despite doing so in the same http request that it errors. Even after reinforcing file permissions of 777 from without and outside the VM, Yii doesn't seem to make further attempts to write the stylesheet.
If I just refresh the page loads without error but the stylesheet bootstrap.css has not been created in the directory.
This is most frustrating. Does anyone have any ideas?
If it matters I am running Yii in a Vagrant VM with Virtualbox. Debian is the VM OS and Ubuntu is the host.
