i'm on 0.9
If i try to select ON or OFF, the settings page comes back as HALF ON only. i have no idea how long its been doing that :-(
my content/cache folder and all contents therein are owned by the webservice (UID 33) and the folders have write permisson for that ownder and so on, so i don't THINK it's a permission issue.
the regular cache files are there and recent, but the supercache folder is empty
(i have gone through the FAQ troubleshooting steps)
