I have been in and out of my site all day, On my last visit, the theme was gone and took the admin link with it! What is left is a page with links for my postings. Clicking SOME of these links takes me to a properly formatted page except that only a single posting appears. Clicking others simply reloads the same page of listings.
From the properly formatted pages I can get to the admin page and from there, have tried changing themes. I get the same results with each theme.
Could someone PLEASE take a look at this and see what you can make of it?
