FIREFOX downloads not working = modules.php

jayblaq · February 8, 2007

I was doing alot of housecleaning over the past few days deleting loads of old data from the database and alot of .bk backup files we made during the development of our site.

Now for some reason when a customer tries to download a product in firefox it does not give them a link to the .mp3, but wants to download modules.php file. i dont know what i could have changed to make this happen. here is the code for my download.php file, please note it has a few mods to make it work. Any idea's?
