I can't upload translation .po file


I’m trying to upload since yesterday the French translation plugin file of Snapshot.

But I get this:

Whoops, this request has been Blocked!

This request has been deemed suspicious and a Possible attack on our servers.

Since I have not had a reply from contact@wpmudev.org I post my “claim” here.

I obviously understands the security problems, I am not at all surprised or offended.

We must say that I have been “very active” in recent days on WPMU and my IP (dynamic) is probably a little exotic …

Anyway, if any of the staff can help me or accelerate the procedure so that I could, I would appreciate it!

Thank you.
