To repeat my initial post:
If the Hosting Volume field says anything other than “vol1_6”, it means something else is going on.
And by “something else going on”, I meant that the issue described in this topic is not the issue affecting you. So please open a new topic in the Hosting Support category (and fill in the topic template please) so we can check what is the issue with your website.
I need more information than “this is not the issue which is affecting me, but my website is broken anyways” in order to help you.
But to update this topic, it appears that the file system is still not working.
