Andrew Smith has a post (found here) in which he attached 2 files:
The zip file downloads quite well, with no problems at all, but the other file’s link just opens a blank page. I’ve tried several times to download the file in different ways (e.g. same page, new window/tab, “save location as…”) with basically the same result. Just a blank.
I suspect that this is due to a failure in the script to determine the correct mime-type for the file, and so simply dies without any output. If this is the case, perhaps assigning the mime-type “text/plain” may resolve the situation with a minimum of hassle. I realize that there will be times when this approach will give unexpected results, but it’s better by far than having folks get a blank page for their efforts.
I’ve suggested to Andrew that he either zip the file and attach the zip file, or change the extension of the file to .txt and try it again. The second method would be best (renaming the file), as it will possibly help to diagnose the problem.
