I just downloaded and am trying to setup my theme into 2.3.0 RC3. However, I get this error for any themes other than blackcandy and tutorial.

None of these templates can be found: Page.ss, ContentController.ss

It's weird too as I can rename tutorial to a different name it won't work either. What could possibly be going wrong?

Try adding ?flush to your URL - this makes SilverStripe regenerate the themes cache.

Hello,

I have the same problem... I installed a few new themes and they doesnt work. Only the blackcandy theme works all other themes doesnt work. I tried to change the permissions of the themes folders like the folder blackcandy and also to add ?flush at my URL, but it doesnt works anyway.

Hope someone can help me?

ok, i found the problem: I've renamed all my theme folders and I found that the theme folders with an "_" in the name doesn't work. When I renamed the folder and tried it again it works.

i have this problem too..i've tried lots of different themes (even ones without a '_' in them like the previous post said?) and none of them are working..it just comes up with the 'fatal error' etc.
i don't know what i'm doing wrong! because i'm doing everything that it says to!

+1 for flushing the cache. :o)

Hi there,

i had the same problem, for me removing the '_' in my template name works!

I too stumbled upon this topic when encountering this error.

Big phat -1 for cache that doesn't invalidate when it needs to! I fricking hate caches in development mode.
