We are recieving an error when trying to upload medium to large image files. Our website just got live 2days ago when we experience this.
I have a paid basic plan in mashape.
If we upload small images like 197x50 with filesize 4.31KB, it’s working fine but not for medium or larger images like 531x336 with filesize 13.5KB.

Did we missed something, how are we going to fix this.

The website is: www.ifastmatch.com

Detailed error:
XMLHttpRequest cannot load https://imgur-apiv3.p.mashape.com/3/upload. No ‘Access-Control-Allow-Origin’ header is present on the requested resource. Origin ‘http://www.ifastmatch.com’ is therefore not allowed access. The response had HTTP status code 500.
