PHP Fatal Error: Call to Undefined Function Curl_init()

Description:

CURL is not enabled in the server.

Solution:

Open php.ini , navigate to ;extension=php_curl.dll (around line 950) and uncomment it by removing the semi colon in front.

Then restart the server.

Also you can check if is enabled by creating a page with phpinfo(); inside. The CURL related information should be there if CURL is enabled.
