I guess you need to activate the php_curl extension to solve your issue.
Please refer the steps to activate the php_curl extension :-
Left click wampmanager
wampmanager -> PHP -> PHP Extensions
If the php_curl extension is not ticked for you then click it and it will activate the extension and restart Apache for you.
It may also be necessary to activate php_openssl in the same way, depending on the theme's requirements.
