Call to undefined function curl_init()

If you get this error, then cURL is not installed properly. To make sure that cURL is correctly up and running, please follow these steps:

• remove ‘;’ from extension=php_curl.dll in php.ini
• make sure that the following lines exist and are properly configured in your php.ini file ; Directory in which the loadable extensions (modules) reside. extension_dir = *some value*
• if this line does not exist in your php.ini, add it
• make sure cURL is properly installed. You should have a cURL file in your PHP extensions folder.
  • For Windows users on Wamp, that will be \Your folder\wamp\bin\php\php.(your PHP version number)\ext ; and the file will be called php_curl.dll
  • Linux users should know how to install an extension. Here is an example for Ubuntu: sudo apt-get install php7.3-curl After installing libcurl you should restart the web server with one of the following commands, sudo /etc/init.d/apache2 restart OR sudo service apache2 restart (taken from StackOverflow)
• run phpinfo() and check if cURL is enabled (you should have a cURL section)
• if you still have some problems on Windows, try this:
  • download a fixed version of cURL corresponding to your PHP version and replace it in the \ext folder http://www.anindya.com/php-5-4-3-and-php-5-3-13-x64-64-bit-for-windows/

Make sure to restart your server each time you modify something in its configuration.
