Hello i need help for setup max players on valheim. Can y help me? 

Up can y help me pls 

how can i see if it really works? Where put this file ?

/umod/plugins Well, check only when more than 10 people come

do i have to have umod inside the server or just this file?

uMod would have to be installed as shown in the guide. This plugin will not work without it being installed.

can i see where is the guide? the umod must be installed only in the server or also in the other players?

uMod is serverside only. https://umod.org/games/valheim/guide

I have a dedicated server. How edit this. sry

You'd need full access to the server to install things, else you'd need to contact your host.

Jhonson, if you have no luck. Try https://goodgamehosting.com, they have it all set up as 1 button.
