Post in search results not displaying

I had this problem a few minutes ago, but worked out how to overcome it and thought it worthwhile posting incase any one else had the same problem.

My lavender plug plants arrived today that I ordered some time ago when they were on 'special' at T&M and there was a free P&P code and I went through Quidco to get cashback.

I thought I'd posted how cheap they were when I ordered them some time ago, so I searched for "lavender" (using search on the top bar) and one of the results was this post (on page 3):

But clicking on that produced the IE cannot display error message, so I deleted the trailing "?highlight=lavender" of that link above, tried again and the post displayed OK. Like this:
