Here is the plugin:- http://mods.mybb.com/view/attach-link

1 week before, it is working fine, when we download a file, it will be downloaded from my other server url, i.e. powerhost.com/myFile.txt
But now, it is downloading as a attachment from my URL, i.e. exmple.com/attachment.php?aid=5

I've checked my uploads folder, but there is no attachment , So do any one know what is this issue about?

Which folder? Uploads, (yes it is 777, but I think its not the case)
Attachments are working fine, as per this plugin, it attaches the link, so the file must be download from that url, not from my server, but in my case, when I attach the url, it works fine for some days (download from other url) but after some time, It shows me the url of file from my server,

in short,
attach link , Download file from :- powerhost.com/myfile.txt
Attachment, Download file from:- mywebsite.com/attachment.php?aid=4

but in my case

attach link , Download file from :- mywebsite.com/attachment.php?aid=4 (the link chnged after some time, but file didn't exist on my website, it is still on powerhost and downloadable, the whole mess is about the url)
Attachment, Download file from:- mywebsite.com/attachment.php?aid=4

The code looks fine to me. Have you setup correct URL? And make sure settings are fine?
