Hmm, OK, I replaced the existing file in wp-admin but I am not sure how to access the upload.php file (nowhere in the navigation), so when I went to the file directly in the browser, I got this:
Warning: main(admin.php): failed to open stream: No such file or directory in /home/lawre2/public_html/blog/wp-admin/upload.php on line 2
Fatal error: main(): Failed opening required ‘admin.php’ (include_path=’.:/usr/lib/php:/usr/local/lib/php’) in /home/lawre2/public_html/blog/wp-admin/upload.php on line 2
