IWD sum/name mismatch

[Lestat]

Hi,

Someone know how to fix or what makes that message "iwd sum/name mismatch" 
when using some mods into the fs_game folder only on Linux server?

I got some mods that when installed into the fs_game they show this error 
when connecting, when I put the mod's file into the main it is working (but 
of course it is not good because player got the file into theyr main) and on 
a windows server it is working without problem

Tryed with sv_pure "0" (into the cfg and confgi_mp_server.cfg) but is the 
same.

So I really need to fix this issue because I don't have so much windows 
server. Can someone help me?

Thanks
