Undefined index: idSites - Piwik 3.0.2

Support & Bugs
1

I just upgraded from 2.15 to 3.02. Install was successful however when I go to Piwik Settings I see the following message repeated about 30 times. I can still see Tracking information for applications but these messages pop up every time I switch to a new app in the Dashboard.

WARNING: D:\wamp\www\piwik\plugins\Goals\Reports\BaseEcommerce.php(56): Notice - Undefined index: idSites - Piwik 3.0.2 - Please report this message in the Piwik forums: http://forum.piwik.org (please do a search first as it might have been reported already)

When I open the PHP file being referenced, it appears be having an issue with this function:

private function isEcommerceEnabledByInfos($infos)
{
$idSites = $infos[‘idSites’];

        if (count($idSites) != 1) {
            return false;
        }

        $idSite = reset($idSites);

        return $this->isEcommerceEnabled($idSite);
    }

Please let me know how I should proceed to resolve these messages, thanks.

I am having the exact same issue after updating to 3.0.4. Did you find a resolution for this?

Hi, @auBusinessDaD

Someone else solved the issue yesterday by updating all plugins: Warning after update

Thanks @Findus23,

I did see this, but how do I update all of the plugins?

5

Just go to the plugin overview in the Admin Interface and check if there are any updates.

6

I am on the Manage Plugins page in the admin interface and can see all of the installed plugins but there is no check for updates button.

7

If there is an update available, it should look like this:

UIIntegrationTest_admin_plugins.png1126×924 91.9 KB

If there are no updates available, you can try to disable all third-party plugins one-by-one until the error is gone and you know which plugin is causing it.

8

So no updates are available then?

Have you tired this? Did it help?

I just saw that there was already a github issue for this error:

The file piwik\plugins\Goals\Reports\BaseEcommerce.php should have been deleted a long time ago in one of the 2.x updates.

The folder should look like this: https://github.com/piwik/piwik/tree/master/plugins/Goals/Reports

Maybe try manually deleting the BaseEcommerce.php, BaseEcommerceItem.php and BaseGoal.php.

11

Unfortunately when i do that Piwik gives an HTTP 500 error.

12

Hi, can you check the error log, to see what the exactly fails?

13

Thank Findus23, where do i find the logs? (sorry not a php or piwik pro)

That really depends on your operating system/linux distribution. But most of the times it is somewhere similar to /var/log/php7.0-fpm.log. If you are on a shared hoster, you often have a logs directory in your FTP folder.
