I am having the same issue. My site is only showing "Apache is functioning normally" If I try to access a page directly like contact.php i get error 404 page not found? I have logged in today to my admin and didn't get any errors so don't think my account has been locked.
Is anybody able to assist with solving this error.
I have just created and imported my website to the x10hosting service.
I get the HTTP 503 Backend fetch failed error when I use my members login form.
Any help is much appreciated.
