I have a blog installed on my site using Wordpress. Last week I upgraded Wordpress from 2.6 to 3.0.4 (I had to do this manually).
All went well, or so I thought, but I have just noticed that the content of an existing page has vanished. The page URL still works, but all content has disappeared - doctype, html tags, body tags, everything.
Please note, this is specific to pages - posts are still displaying fine.
I have since created a brand new page which does not display the content either.
Things I have tried include
* Switching to a freshly installed theme * Reverting the page to an older version * Deactivating all plugins * Setting the problem page to draft, and back again * Deleting the .htaccess file
I suspect it's a database problem and have contacted my hosting company who have said the only thing they can do is restore the DB from a backup, but that I should consider it a last resort.
Does anyone have any further ideas what to try?
