My problem is that i'm runnning an new version of WP, 2.9.2, in danish. I have uploaded a theme i'v created myself, which for some reason doesn't show up in the theme selection page. I've checked that the theme is uploaded to the webserver.
I've tested the theme on MAMP locally, on the same version and language of WP and it works fine. Other themes work fine. I've cheked for hyphens and addtional folders etc.. WP is working on the server: http://s-indreby.dk/
The entire theme is here in a zipped version.
Thanks for helping!
