GRRRRRR

I am having some serious issues with this blog again!! I can only see 1 post, and can't find a way to show several posts again as it always has done.  I have wasted a lot of time searching for ways to set these things, things that used to be here for changing the look of the blog, etc, but with the new set ups Blogger has developed, I can't find any way of setting up my blog the way I want it. GRRRRR.
