since upgrade this morning, redirects? and no more browser friendly

second time, writing here, first time “no title” so have to start again, i really hate the updating process–it has cost me –almost every time.

so i got a plug in that auto-updates.
the blog seems to working, and I was able to edit a post i made before the update, but it is confused
there is a redirect showing up in the browser bar, and it is no longer a “friendly” type–(lots of percentage signs etc, and my title no longer shows up in the very top of page of the window)

to ans these questions for you
i do have backups
i also have feedburner

any advice please?
