Wordpress image upload issues over https?



Hi I have a very strange behavior in one of our theme. One of our customer enable https in his site. When you are logged in as site administrator you can upload image from the front-end dashboard. But there is another user role and that is company_owner who can’t upload image from the front-end. Can anyone help me with this issues. But with http it just work fine.

After uploading complete it show an error: "An error occured when sending. Please try again later."
If you have encountered this type issues before then please do help me with this.

Thanks in advance.
