Every time I go to Products > Categories I get a "blank.html" file downloaded to my local machine. Then, as I setup categories and click the Save Category button another "blank.html" file downloads to my local machine.
Here is a screen shot of what happens when I go to the Categories section of the backend (notice all the download "blank.html" files in the browser status bar) --> https://drive.google.com/open?id=0Bytqhoir_Tt5dFYwcUxGeExGUHM
Here is a screen shot of my downloads folder on my local machine --> https://drive.google.com/open?id=0Bytqhoir_Tt5SDU5b3FjZVdmYkE
How to shut that feature off?
