How to increase the maximum length of titles in Excerpts?

When you say the title, I assume you are not talking about the 55 word default of the body of the excerpt? If you are referring to the body text, read this (about halfway down the page)

Thanks, but I’m talking about the title itself. In other words, the title above the excerpt. It gets cut off after a certain number of characters, which I’d like to extend.

Note that when the excerpt title is clicked, and they go to the actual article, the full title is displayed.

You can see it in action here:

radiovalencia.fm

As of typing this, 2 of the posts have truncated titles.

the shortening of the excerpt titles seems to be some custom code in your theme;

try to find the excerpt section in the code of the front page template (index.php ?) and see if the title uses a special code.

Right you are, thanks, found it exactly where you said it might be.
