yes, you can download it as a static tiddlywiki and it's a classic version.
1) I am not sure why you can't update to tiddlers? Do you mean you
can't save it? If you can't save then it might be a tiddlyfox issue.
Try to restarting.
2) Try to upgrade the downloaded TW into TW5 because the classic
version won't work as TS. The backstage menu is brought from TS.
I am reposting what I did here,
Steps on making static backup of your TS
I am in the process of making manual backup of my TS. My method is
done by making an offline copy of my TS and to convert it to recent
version of TW5 thus providing a static backup. At least this is
something that I can do before trying Mario's script.
I made a download copy of my TS using the export function from the
backstage and it turns out to be a classic version 2.8.1.
I use a recent TW5 empty.html ver 5.1.13 and imported all the tiddlers
from here and importing works as a charm. It showed incompatibility
issue because of its classic version which can easily be rectified
using the upgrade button to each.
"This tiddler is written in TiddlyWiki Classic wiki text format, which
is not fully compatible with TiddlyWiki version 5. See
for more details."
Tiddlers with images (say imagex.jpg) and TS related functions can not
be upgraded and need to be discarded.
Then I renamed all the title related in the control panel to identify
it as a new TW under TW5.
Let me know if you are eager to preserve your TS using this method.
