I released a new version that fix a bug for who choose save css as files.
The problem here is that your categories are not actually categories..
They not "act" like a category, they act like a forum.
tomorrow I will try figure out how to apply my hack in this situation.
The problem here is that your css is stored as files..
I've fixed that, download version 1.2 which I just released.
Currently I have no demo to display, sorry
Thanks

I will release an update for older versions in a few days
Maybe you choose save your css as files, I fixed that in version 1.2 .
please update and see if it work now.
If not, please send me a message.
