Posts not displayed but everything else is??

I’ve just logged into my site and tried to access a post but once you click through the main page nothing is displayed on the post page.

The home page and all the sub category pages work http://www.theothersidemag.co.uk/topic/film/ but when you click to read a post nothing shows up for example http://www.theothersidemag.co.uk/2010/11/the-kids-are-all-right/

I’ve tried disabling the plugins but to no avail.

any help would be so much appreciated, thanks

Sam
