But when i try to do the 4 step, y dont have the same options in my dashboard...I have this one (the image attached)

Please make sure you're using the latest wpForo version (v. 1.6.1). 

Now when the user post any topic, it doesnt need any aprobation, but this user can aprobe o desaprobe any topic and i dont want it, how can i change? 

It seems you've enabled the "Can approve/unapprove content" permission/CAN. Please navigate to Dashboard > Forums > Settings > Forum Accesses Tab, edit the Forum Accesses and make sure the CAN is unchecked for all accesses, except Full and Moderator once.

Please read this article on How to Disable Topics and Posts Moderation in wpForo:

Im working on a new forum and i dont want to moderate all topics. When anybody opens a new topic the moderator has to aprove that topic, and dont want that. I need it to be published automatically without moderation 

How can i change that? 

Thanks :)
