I'm using ewiki inside of Moodle 1.6 and there's an issue with headers not being set correctly for file downloads. I'm getting the "Check file/path name" errors when trying to open attachments to the wiki in IE6. I know how to fix it in the code, I just can't find where the headers are being set for file attachments. If somebody could tell me where this is happening in the code it would be appreciated. Thanks.
