First of all, the front end of the site is fine. All pages and posts can be accessed.
I can also logging to the backend without issue. However it shows 0 posts and 0 pages. Nothing at all. I've checked the database and the content is all there. I've also used the admin bar in the front end to try to edit the page but all I've gotten was a "You attempted to edit an item that doesn’t exist. Perhaps it was deleted?" error message.
I've checked with the hoster and got the usual reply that I should upgrade wordpress and the plugins. Considering that the site worked a week ago with the same plugins, I fail to see why that would be the cause.
Any advise? Thanks in advanced.
