Having a weird problem on a new site we are putting together. Everything is working OK with one exception - one page always returns a 404 page not found.
In the admin pages, if the page is veiwed or previewed it works fine - in fact, if I open the site in another browesr tab - the site works fine. As soon as I log out of close the admin page, the very same page when refreshed comes up as 404 page not found.
I've tried the ususal disabling plug ins, even tried refreshing permalinks - which was a disaster as the category posts on the front page started showing all the text instead of just the featured image. Its back to "normal" now - but even creating a new post with the same name doesn't work
I really don't understand whats going on here - seems to have a mind of its own!
Any ideas would be greatly appreciated - although seemingly a simple problem is is proving to be a show stopper!
