Client’s Issue:

Hello, can you help me on one urgent thing:

I have the website: www.hallgrimur.is

When I was taking a look at it this morning, I saw that someone set up a new but empty blog post.

1) It is very strange because no one has access to this blog page except me

2) How can anyone access my blog page and put in this “new” blog post?

3) Can you delete this blog post? I cannot do it… I only get error!
