I just installed JoomSEF everything look ok, I see a bunch of links, but when I go to my site I can not access those links, 404 error.

I read most of the messages here in regards this issue, but I dont get it, I see a lot of diferent info... Can anyone explain this process in basic english, or maybe in spanish for that matter...

I cant get this to work, I need someone who can help me... I have at least 10+ domains that I want to do this process, so I need to know how///

thanks so much

REWD,
