I seem to be having a somewhat unique issue as I have not been able to find anyone else with similar issues. I've installed attachments mod on my site. Everything seems to work as it should but when I attempt to download any of the files, they are all corrupt. By that I mean if it's a text file all I get is the page source data. If I download a zip or rar file, I get a message saying file is corrupt and images I get file format can't be read.
However, if I go to my attachments folder and rename the file to it's original format, I can then open the file and view it as I should. So what I am getting from this is that the file is uploaded and stored correctly but when I download it is where the issue lies.

Any help with this would be greatly appreciated.
