Can not set permissions in settings

Hello!

I cant set permissions because there are no red or green circles in the settings:

My server:
PHP Version 5.3.8
MySQL 5.1.56
GD Support enabled
GD Version 2.0
FreeType Support enabled
FreeType Linkage with freetype
FreeType Version 2.4.2
GIF Read Support enabled
GIF Create Support enabled
JPEG Support enabled
libJPEG Version 6b
PNG Support enabled
libPNG Version 1.2.44
WBMP Support enabled

piwik is installed in a .htaccess protected folder (if that matters). What am I missing? Thanks.

Update to most recent version of Piwik, and check that all images are uploaded correctly

Thank you Matt!
My PIWIK is up to date und when I look at the folders and check with Firebug it says the images are there and nothing is missing but the images just wont show up in the browsers. Ive got no clue whats goin on.

check your .htaccess allows the images through, e.g.,


<Files ~ "\.(test\.php|gif|ico|jpg|png|js|css|swf)$">
Satisfy any
Allow from all
</Files>

Thank you. After the installation I had to delete all the .htaccess files because on my server .htaccess files are not alowed for security reasons.

After deleting all the .htaccess files in the piwik folder, all the images and icons show up and I am able to configure piwik.
