problem with updates not showing – posts and themes

I’m running WP 2.7. When I use any browser aside from an install of Firefox on my main PC no posts show up on my blog at https://monaxle.com since the one I posted on the 10/12/08. Everything looks as it should to me when I go to my blog in Firefox on my main PC (which I use to administer the blog / FTP and so on) but on no other PC or browser I’ve tried.

I’ve not tinkered with the code in the theme I’m using https://wpthemes.info/misty-look/ so don’t think it could be that.

I’ve tried restarting my server and reinstalling WP both with no luck in solving the problem.

The admin screens tell me my posts have been published. How come they are not showing up though? The only other thing that’s a bit odd is that the meta widget and recent posts widget do not have the option to add them to the side bar as in it appears they have already been added but they have not!

If anyone can offer any ideas that would be great. Thanks.
