Upgrade wp to 2.2 with Simple T theme

So in Administration > Options > Reading you set the Show at most [X] posts to one (1)?

I have already done that and it doesn’t work! I have tried another blog and it works so It has to be with Simple T theme, I don’t know what do I have to modify?

I wonder if the Custom Query String settings are overriding that?

How should I configure Custom Query String, I have it as with wp 1.5 and it worked before.

I think it’s the WPpaginate plug-in. When I deactivated it, then it only displayed one post.

Thank you brookston I have done what you said and now it works!!
