Yes, it comes up with an error 404 or that it can’t complete drawing up the page.
Looking online, it could be a plugin issue, a theme issue or any one of a million other reasons.
In my case, I cut and past some text into a blog that contained an unprintable formatting character and it brought the while thing down.
So if anyone gets this issue, look for strange little squares in your posts. It might save you lots of pain !
