Hello again! Found that pesky random line on my media pages today! Could you please provide code to remove it?
Example: Alia Bhat IIFA
Thank you for your question.
You can remove it by adding the following CSS code in the Custom CSS option of your theme on the below path.
Admin Area -> Appearance -> Customize -> Additional CSS
.attachment #page .post-inner-content {
border-top: 0;
}
Best Regards,
Movin
Thank you! 
You are most welcome here
