"Visit Over Time"-chart does not update

Hello there

I’m having troubles with the visits over time chart. Since I moved piwik to a linux-cluster the chart does not update anymore. Actually, it does log the visits you can see that in in the widget visitors in real-time.

I updated Piwik to the version 1.12 but this does not help neither.

I would be glad for any help and ideas.
does anyone know which script does generate the visits over time chart?

Thx a lot.

Setup the archiving cron: How to Set up Auto-Archiving of Your Reports - Analytics Platform - Matomo

Thx!
Okay, if I run that script I get that:

What could that be?

some more infos:

in the archive.php…
if I quote following section:

    // Test the specified piwik URL is valid

// $response = $this->request("?module=API&method=API.getDefaultMetricTranslations&format=original&serialize=1");
// $responseUnserialized = @unserialize($response);
// if ($response === false
// || !is_array($responseUnserialized)
// ) {
// $this->logFatalError(“The Piwik URL {$this->piwikUrl} does not seem to be pointing to a Piwik server. Response was ‘$response’.”);
// }

the script can be executed but the output is also not satisfying:

ERROR: The Piwik URL http://piwik/index.php does not seem to be pointing to a Piwik server.

It means that http://piwik/index.php does not load Piwik. For the script to work, you must specify URL to Piwik.

Hi Matt

Yes, i specify it. This is how I run it:

/usr/bin/php /var/apache1/vhosts/piwik/misc/cron/archive.php --url=http://piwik/

when you open http://piwik/ does it show Piwik login form?
