I've done all the required steps in Twitter Dev tools to set my blog up as an app to use Twitter tools. When I post it's still not sending my posts to Twitter. I made the access level read-write, inserted the consumer key and secret, and access token and access token secret, and updated the plugin settings. Still nothing.
Fatal error: Call to undefined function curl_init() in /home/namcheol/www/wp-content/plugins/twitter-tools/twitteroauth.php on line 201
