Pages Displaying But Not Posts

Hi there,

I am having issues with a blog that has been running fine for the last few years. There have been no major upgrades or changes done recently and no new themes used but the blog has been getting progressively slower over time.

Now I find somewhat bizarely that whilst the pages of the blog will display fine, clicking on a permalink to any posts won’t display them. They appear fine in the dashboard when I go to manage them. So pages are fine, posts aren’t.

I’ve searched the forums here without luck for any suggestions. Obviously with a decent amount of traffic I’m keen to solve this issue as quickly as possible. Has anyone seen this before? Can anyone make any suggestions to me?

Many thanks.
