Problems with Database and reinstalling?

Hi everyone,

A while back I setup a little blog for our software company Editor Software at http://www.editorsoftware.com/wordpress/

All went great, modifying the theme was easy. All was good.

Then recently we went through some changes, I changed some server settings, and suddenly the posts aren’t loading. A new post loads, but past posts won’t.

I’ve checked the config file, and the username and password matches the server admin password (which the MySQL databases match). So I’m at a loose end 🙁

I was going to try and reinstall from scratch and see if that fixes it. I just wanted to check first if there were any last options I could do before reinstalling?

Also, assuming I want to reinstall, I assume I can just copy the theme folder and paste it into the reinstalled version once I’m done to keep the look etc?

Any other advice would be appreciated 🙂

Cheers,
Saul.
