Ok so not long ago I uploaded mantra onto my site to be used for the theme. Everything seemed to be working fine till I attempted to change the image in the header of the page. Normally I Wanted to have it as a banner becuase I was unable to figure out how to upload it as a banner and have it as the only thing on the top of the page. Since I couldnt find the banner option I decided to have it as the header and not have an text over it. The only issue with this is that whenever I try to upload the image from my media library (Image is already uploaded and saved) is that whenever I click the button to upload the image the whole wordpress page for Header goes white. My browser does not crash because I am able to go to other categories and everytime I got back to the header page it is back to normal with the only exception being that the image was not uploaded.
