Cron issue with shared hosting

Question

CiviCRM 4.6.7

I get an error with this command: wget -O - -q -t 1 'http://www.website.org/wp-content/plugins/civicrm/civicrm/bin/cron.php?name=user&pass=password&key=site-key'

Fatal error: Uncaught exception 'Exception' with message 'Function "is_admin()" is missing, even though WordPress is the user framework.' in /var/www/vhosts/website.org/httpdocs/wp-content/plugins/civicrm/civicrm/CRM/Utils/System/Base.php:258

Thanks for helping.

Edit:

With CLI PHP I get this error:

Answer 1

I have resolved the issue. The path to the wordpress directory was wrong, don't know why. I have changed hosting during the week.

I had to add this line in civicrm.settings.php:

define('CIVICRM_CMSDIR','/var/www/vhosts/website.org/httpdocs');
