Piwik suddenly stoped showing the websites list

hi,
my name is amit and I’m using piwik for about 2 years from now.
today when I loged in to my piwik I I couldn’t see the list of the websites.
as you can see in the picture I attrached it still working (I can see by the total visits that keep rising)
I can connect the settings but can’t save any, and I can’t change the date.
tried to log in in a diffrent browser includeing delete cach&cookies, also tried to replace the files of the default theme. noting worked.
please help.

Try bumping up the memory limit in php.ini and the apache server itself does that help?

I changed the memory_limit from 512 to 1024 and it still no working

ok What browser are you using? have you tried in anther browser? Is it in just this view you have an issue? tell us about teh server environment.

I’m using ubutu in web browser firefox and chrome.
as I wrote I can connect the settings but can’t save any, and I can’t change the date.
about the server:
System Linux 2.6.18-408.el5.lve0.8.58 #1 SMP Wed Mar 14 14:10:01 EDT 2012 x86_64
PHP Version 5.3.10

Have you checked the user settings as far as if they have all permissions on? Maybe turn them of and then on again to see if that helps.

Please update to the latestr version of Piwik ! it looks like a bug we fixed in the last version ?

problem solved!,
I replaced all piwik files to fresh installation.
and remove cach from my browser.
thank you all.
