I've installed nginx and everything works nicely... until you try to make two things:

- send a privatemessge or
- send a friend request relationship

it sends the forms, but aparently the browser keeps runing for a while until brokes showing this message:

504 Gateway Time-out in nginx
The messages and the relationships are sended, but the server seems not to respond after clicking the submit buttons.

I've tried to increase the timeouts, no luck.

Any idea?

Thanks a lot in advance.
