[solved] Can't change template

[Joonsen]

Hi,

I copied and pasted the standart template and renamed it.

I can change the css files and everything works.

But when I try to change the .tpl files, like header.tpl, nothing happens.

I have chmodded 777 the needed folders like shown in the wiki.
And I have chosen the new template in the backend.

I use the german prestashop from prestashop-germany.de

Can You help? I am really stuck here.
Did I forget something?

$smarty->force_compile = true;
