I use Twenty Eleven theme and made a child of it. I just tried changing my Permalinks to Post Name but whenever I try opening my very post on my website I get:
"This is somewhat embarrassing, isn’t it?
It seems we can’t find what you’re looking for. Perhaps searching, or one of the links below, can help."
All other posts work fine. It's only the first one that can't be displayed. I then tried to change Permalinks to Numeric and it worked fine again.
How can I change it to Post Name again? Google Analytics is worthless to me if I can't see the names of the pages that people visit the most.
Thanks in advance.
