Before Christmas our self-hosted WordPress site ( http://www.sabretrust.org/blog ) was working fine and we could log into the admin area to make/edit/delete posts etc.
Since returning from the Christmas holidays it seems that we are now unable to reach our log-in area (http://sabretrust.org/blog/wp-login.php) and the blog no longer shows as a valid page at its address (sabretrust.org/blog).
Would someone please be kind enough to let me know why these problems have arisen and how we can fix them to get back to things as they were?
Interestingly I can still access our previous posts via the iPhone app although an error message does appear which says:
Expected status code in (200-299), got 404"
I am none the wiser. Any help would be most appreciated. Many thanks in advance.
