Please watch your language. We all know what WTF means and there is no need to use that on our forums what so ever.
I moved your post to the correct forum for web site issues.
Now could you give more details with the problem you experienced. The name of your mod, what category it was in, when you tried to update it, file size, etc. Does it show up on your personal interface list (use the link on the main menu on the front page) That will help me track down what is going on.
Its possible your interface was lost if the file upload didnt finish or was corrupted. I dont see any interfaces from you in our database at the moment but it shows you had one because you have the interface author tag under your name. So I think you'll need to re-submit it as new.
Thanks.
