I have a relatively new site at kianschi.nl on Wordpress 3.3.2 and with the addthis plugin version 2.4.0.
I can use the site and the Wordpress Dashboard/admin pages fine when I'm logged on using an admin level account, but as soon as I switch to a non-admin account I receive the following error when trying to go to the Dashboard:
Fatal error: Call to undefined function apply_filter() in /home/kianschi/domains/kianschi.nl/public_html/wp-content/plugins/addthis/addthis_social_widget.php on line 769
When I deactivate the addthis plugin everything works normally.
This question is closed to new answers.
