Ok I'm a total novice at this and I've made a big error. I brought my WP.com blog over to my WP.org website today and it seemed fine. But the posts weren't appearing on my 'blog' page. I didn't know what to do, but the permalink seemed weird it was http://www.kdconceptsweddingstationery.com/http://www.kdconceptsweddingstationery.com/about
So I changed the permalinks to date and title. But the posts still didn't appear on the right page. So I didn't know what else to do.
I looked under Settings, General and there was a bit about the URL for WP and then another URL for the home page. (which were both http://www.kdconceptsweddingstationery.com). So I thought I'd change the WP one to http://www.kdconceptsweddingstationery.com/blog and now everything is a mess! My site doesn't look right and I can't login to WP. I didn't think it would cause so much trouble! I tried to change it back when I was in WP but it wouldn't do it and now I've logged out and can't get back in. Can anyone help me please? Please.
