Had a server go down recently and just reinstalled IIS and replaced inetpub with the backed up files. What's odd is on internet explorer certain div fields have a green background now and all direct links to files are prepending filedownload.php/path=. The website acts completely normal in Chrome and Firefox. For example a link that starts as:
https://$company.com/$foldername/$file.xlsx
Turns into:
http://$company.com/file_download.php?path=http%3A%2F%2F$company.com%2F$foldername%2F$file.xlsx
And obviously doesn't work anymore. What's odd is in the code it's just pulling the link from a MSSQL database row/column, no interpretation or funny stuff.
