How can I break an infinite redirect loop?

I just deleted a page on my wordpress site. The page was not a sticky, but it always appeared as such when you went to the site.

I noticed that the link name for it in the dashboard editor was the site name ie without a specific name for the page. Which I thought was a bit odd, and may have something to do with the problem.

I had a post which was a sticky – this was actually the one I wanted displayed, but it was never displayed. Instead the page above was always displayed when you went to the site.

Having deleted that page, I now get an infinite loop.

I was not using any redirect plugins.

Ive tried the following solutions:

– installing the redirect plugin, but no difference. There are no redirects listed in the plugin.

– deactivating all my plugins.

– installed a plugin called Permalink Fix & Disable Canonical Redirects Pack. This is said to be only for WordPress installations residing on Concentric/XO Communications shared hosting platform only. It did at least let me reach the site without a redirect loop, but it just says 404 page not found.

– tried removing the sticky post status.

– tried changing my permalink structure. I was using the default. Ive tried custom and other combinations.

– tried switching to the basic wordpress themes.

– cleared all browser caches

– reinstalled WordPress 3.3

All the above have brought no solution.

So the question now is, what else can I try?

Is there some file that I can edit by hand to solve the problem or something?

Thanks in advance for any advice!
