Admin links redirecting to deleted blog

Hi. I looked through the forums and couldn’t find my exact problem there.

I had one WP blog installed on my site and added another one. I used the same database, but created different prefixes for both blogs. When I would be logged into the first blog, it would sometimes redirect me to the other blog – even though I wasn’t logged into it. I deleted the new blog. I cleared my cache and history. I re-installed my saved database, which should have gotten rid of the other blog, then upgraded the older blog to WP 3.3.1.

When I am in the admin panel, I sometimes get redirected to the ghost blog. If I hit the back button and try the link again it may give me the one I want or send me to this ghost link. There is no rhyme or reason to this. Sometimes I am redirected and sometimes I get the correct page.

An additional weird thing is that when I am looking at the blog I sometimes get the blog completely without my style settings until I hit the refresh button. I have tried this on my computer and my wife’s with different browsers.

Does anyone know what is going on?

Thanks!
