<![CDATA[--disk-cache-dir + user-cache + --user-data-dir not working]]>Hi!

I cannot get it working.

--disk-cache-dir

Opera don't create in: "/path/to/.opera-tmpfs/opera/cache"

Error message in Terminal:

Failed to create directory /path/to/.opera-tmpfs/opera/cache
Simple Cache Backend: wrong file structure on disk: 1 path: /path/to/.opera-tmpfs/opera/cache
Unable to move cache folder /path/to/.opera-tmpfs/opera/cache to /path/to/.opera-tmpfs/opera/cache/old_Cache_000

The folder .tmp have user r+w access. My small partition of 4GB is a RAM-drive (Ramfs)
How can I fix that?

opera --start-maximized --disk-cache-dir=/tmp/cache
and it does work

$ ls -R /tmp/cache/
/tmp/cache/:
opera

/tmp/cache/opera:
Cache

/tmp/cache/opera/Cache:

So please make sure the directory you use exists and you have writing access to it. I use the one mentioned above because I keep my /tmp in ram.

---edit---
The parameter --user-data-dir does not work probably due to the lack of profiles on opera.

The path needs to be somewhere that you have access to, hence somewhere in either /home or /temp.
