|
|
* Configuration:
|
|
* Add the following lines to your .htconfig.php file:
|
|
*
|
|
* $a->config['piwik']['baseurl'] = 'www.example.com/piwik/';
|
|
* $a->config['piwik']['siteid'] = '1';

|
|
*
|
|
* Change the siteid to the ID that the Piwik tracker for your Friendica
|
|
* installation has. Alter the baseurl to fit your needs, don't care
|
|
* about http/https but beware to put the trailing / at the end of your
|
|
* setting.
