All pages displaying home content

I’m in the process of building a website for my dad and did quite a bit of work on it last night. Then this morning, all the pages are displaying the content for the home page (I swear it was all working fine before I went to bed). Here are the recent things I did:

1. I made the home page a static page (and moved the posts to another page – in the reading settings). Undoing this does not fix the problem (it just shows the first post on every page rather than the content of the “home” page), but when I first did this, I had to create a page entitled “Home” since there wasn’t one. I wouldn’t think that made any difference.

2. I updated the php.ini with the following:

[suhosin]
suhosin.post.max_vars = 2000
suhosin.request.max_vars = 2000

This was to address an effective server limit on the number of menu items as documented here. It didn’t seem to effect my menu problem (I’ve got a note into my ISP asking about why that is) and undoing it doesn’t seem to affect this problem.

3. I added a bunch of useful plugins that I have used on other wordpress installations (All in one SEO, statpress reloaded, bad behavior, etc.). Deactivating all the plugins does not resolve the problem, though I may try deleting them and seeing if that helps. This was the last thing I did before I went to bed.

Do any of you brilliant folks have an idea? I’m using the twenty-ten template (with some css modifications) if that helps (wordpress 3.1).
