A sample theme from here, which I followed to the letter, doesn't show up in the selector.
I searched this forum and found some common problems and solutions, which, unfortunately, don't seem to apply in my case.
My Moodle 2.0.1 installation is running on a server that I have root access to. It's Ubuntu 10.10 server with PHP 5.3 and MySQL. Theme directory is set to 0755 and is used, because I dropped some other themes there and those do work.
I enabled Designer mode and Debugging messages, purge all caches regularly, checked theme's php files syntax etc.
I don't know where else to look for mistakes, really.
Can someone help me out here, please?
