Hi Tony
Thanks for your reply.
Ha! The "myusername" thing is just me being anal, sorry! I took my real username out and stuck that in when I pasted the error mesage.
I did look at the databases and no, no wp_categories exists.
I read somewhere, I think the WP Support site, that from version 2.3 onwards this shouldn't actually exist?! Don't know whether that is right or not.
The info is obviously in there somewhere as, like I said, the categories do show on the site itslelf.
Another thought I had was the WP Admin dashboard etc didn't update, but that's not the case it is showing correctly as v.2.5.1 too.
I tried to create it at the bottom of the page but it just asked me how many tables? and that's as far as I got because I have no idea what that means!

So didn't want to mess things up even more.
Unfortunately I am having another problem with the site too and I don't know if it's just me or global. It been going on a while now and I always thought it was global but as of a couple of hours ago I'm not so sure. The site quite often goes down. I can't access the site, wp admin or any email a/c on that site. I always thought it was a hosting problem but they claim all is fine.
However, this morning I asked I wife whether she could get into the site at work and she could, no problems. So it looks as though the problem is with just me and maybe it always has been.
Have no idea if these two problems are related or not (can't see how myself, but....)
The site I'm working on and trying to set up properly is called
The Soccer Blog
As I'm typing this, I still can't access it, can you?
Many thanks for your help.
Cheers
Rik
