Check for update -- 2.1.0 is up to date?

Hi, I still haven’t fixed the problem of my previous post , so it may be
because of this, but anyway, when I “checked for unpdates” piwik says it is up to date, and then I get the following error

. Please report the message (Piwik 2.1.0) and full backtrace in the Piwik forums (please do a Search first as it might have been reported already!).

About Piwik 2.1.0

I fixed the other issue (basically by getting rid of all generated .htaccess file, I had incorporated contents of .htaccess in httpd.conf), but I still get the same errors. Any thoughts?

If you get this error: php_network_getaddresses: getaddrinfo failed: Temporary failure in name resolution

it means that somehow your server cannot contact our server: http://api.piwik.org/1.0/getLatestVersion/

Maybe try to restart your webserver and see if you still get the same message?

Thank you very much. It turned out that our ISP updated the firmware of ADSL modem-router which messed up LAN configuration,
all I had to do is to edit the /etc/resolv.conf file of the server (since the server doesn’t do anything other than hosting
our website, I didn’t realize this before…
