In the admin panel all of my published pages have disappeared. 'All' & 'Published' show the number 56 which is correct but the pages do not appear in the list.
At first, the pages (except for the Home Page) would not work when browsing the site, however, when I changed to the default permalink setting (was previously /%postname%/) they worked again but they still don't appear in the page list in the admin panel.
All of my posts and custom post types are working fine, this has just affected the pages.
Also, the wp_posts table in the db just hit 1000 lines/entries. That might be completely irrelevant but it just seems like a coincidence that everything worked fine until now, then it just breaks at 1000.
