I don't speak English vey well, so sorry for my mistakes.
Mi problem is that for each article I want to show just a little summary, not the whole text. I selected the option "summary" from Settings>>Reading but all my page keep showing the full articles except one. There´s no reason for this single article that only shows a summary, just the beginning of the full article.
At the bottom of the reading settings says "Changes may not appear until you create a new post or your news reader refreshes."
I created a new post and changes didn't appear.
--------> What does it mean to refresh the news reader?
The blog I need help with is despachodetaller.wordpress.com.
