Users are reporting a problem with the AddThis WordPress Plugin v6.2 due to a compatibility issue with PHP 5.3 and earlier. The error would look like:
Catchable fatal error: Argument 2 passed to AddThisAdminUtilities::enqueueNotice() must be an instance of callable, array given, called in /htdocs/wordpress/wp-content/plugins/addthis/backend/AddThisAmp.php on line 97 and defined in /wordpress/wp- content/plugins/addthis/backend/AddThisAdminUtilities.php on line 33
To fix this issue, you’ll need to either:
- Upgrade to the latest version of the plugin. It seem the issue has been resolved in v6.3 of the plugin.
- If you can’t upgrade or disable the plugin, you’ll need to find a way to delete the plugin from you server. If you have FTP or SSH access, you can find the plugin in the content/plugins directory and simply delete it. That should get your site up and running again.
Hope this helps someone out there.
