duplicate posts on individual blog post page

hi,

I’m currently having a really weird problem on my blog. WP is displaying the same post twice whenenver I view the page for the individual blog post –

https://www.desertofmydreams.com/?p=4518

It doesn’t show duplicate posts on the home page or any of the archive pages – just the blog post page. I only noticed this a couple of weeks ago. At the time, I was using 2.0 – I upgraded and I thought that fixed it but the problem has returned! I’m only running one plug-in – Akismet. I disabled Akismet and that didn’t solve the problem. I also switched to a different template and that didn’t solve the problem.

It almost seems like some sort of looping issue but I’m not very familiar with PHP or MySQL. Any ideas?

thanks!
Noor
