Comment on Custom Posts Widget by Ratanak.
I moved,the & code and it worked now. In fact, at my sidebar I did not place the Single Post Widget. I just put the SEO post widget but I allowed to display only one post.
At the home page, there are many posts and they are separated by “stseparator” when I use the google code check. I don’t know how to delete that line so that it would look better.
The Single Post widget does still not work yet. I don’t know why too.
Thank you, and hope you understand my question.
