Burp suite

Hi everyone. N00b question but can anyone help me out. I am working on a retired box, Bank and have enumerated and can see a page where I could upload files for a shell.

Except… I always get redirected (302) to login page when I try to go to that page. The original page (support.php) is viewable in the http history of my Burp but I can’t work out how to access the page. I have now looked at walkthroughs where it says to use a plugin, but the NoRedirect plugins for FF won’t work for me. I have tried all the settings on Burp CE and nothing seems to prevent the 302 redirect! But it seems like such a simple problem.

Could anyone help before I throw my laptop across the room??
