Detail

If you have a custom HTML form dealing with attachments, or there is a bug in the Attach page, you may try to change properties of a nonexistent file. For example, the following form can cause that situation.

<form method="post" action="%SCRIPTURL{upload}%/%WEB%/%TOPIC%">
|  File:| <input name="filename"> |
|  Comment:| <input name="filecomment"> |
<input type="submit" name="changeproperties" value="Change comment and properties only">
</form>

The above form can cause the following attachment list:

I Attachment History Action Size Date Who Comment
Text foo.txt   manage 0.1 K 1970-01-01 - 00:00 UnkownUser foo

This usually doesn't happen. But may happen. And you need to manually edit the topic file to remove the phantom attachment.
