Finally, I got Shimmie 2.2.4 to work properly. The first time I tried to install Shimmie was on a webhost that had no PHP5 support, so fail. The second time was on another host, and luckily, it has PHP5. So you’re supposed to allow the web server to create folders and edit stuff by itself, CHMOD 777, didn’t realise it was supposed to be done that way -_-.
Anyway, now it is up and running, but I’m still testing it. Site can be found here: http://mayu-genjo.com/testbed
