Pages stopped displaying

Hi there,

very strange one here.
For some reason my wordpress blog has stopped displaying pages. There was no new plugins installed, i had gone in updated a page and then the next thing I noticed the pages list was no longer available.

So far to troubleshoot I have:
– restored the database from good known copy.
– not made any changes to the theme files and confirmed this by comparing the files from the live site to those on my local environment.
– disabled all plugins

Im all out of things to try… Anyone had a similar experience?
