Enable to download files.

[THaKN]

Hello,

I got the following problem.

I got a Gameserver running.
We hafe a nice mod witch we want to offer
but when i give someone the link to the file it wont download.
i have found the problem.
i wont let anyone download a file with the .flmod extension.
the .flmod extension is the problem.
i can download the same file without the .flmod extension.

i had an other server manager before i had Plesk (got plesk 3 days now)and there it worked fine. it downloaded the .flmod file without any problem.
how can i add the .flmod extension to a trusted extension list ?

now all i get is a 404 (file is there 100% sure about that becouse when i make a copy of the file in the samefolder but without the .flmod extension then i can download it.)

pls help me.
