What I mean is that some news are not showing an excerpt at all, even if they have content. You can check it here: http://larepublica.es
If you open the article, they have a text in it. SO why would it not show an excerpt?
For example, this one is not showing any exceprt when listed in the site.

See:

Might be due to the errors on your page .. check F12/console in Chrome to see errors from your ad modules. Try turning off the bad ad systems being used and see if excerpts work or not.
Two twitter errors and one serving-sys.com error so far found in one click.
Perhaps you should try turning off plugins to see which one causing the problems.
Hi,
do you have any excerpt (spaces or other characters) entered here?: http://screencast.com/t/e2pqFynmC9CE http://screencast.com/t/gvo79gUa3j
The manual excerpt overrides the auto generated one. For the posts that don’t have an excerpt there are two possibilities – the auto excerpt did not manage to extract the info or there is a manual excerpt like a space ‘ ‘.
