I’ve just updated to the newest version of the Facebook plugin (1.2.2). After uploading the new files to my site, I’m unable to login to my WordPress admin (through wp-login.php). The following message appears in the browser:
Fatal error: Call to undefined method Facebook_Loader::app_access_token_exists() in /customers/5/f/9/living-fitness.co.uk/httpd.www/blog/wp-content/plugins/facebook/admin/settings.php on line 38
Does anyone have an idea what has happened and how to resolve?
