@funkster – was this after an update to 2.8 or after updating YARPP to 3.0.6? 3.0.6 changed the excerpting algorithm used from being a custom one to the builtin wp_post_excerpt() function. Perhaps this is why you’re seeing a change in behavior.
There’s an excerpt length option on the options page… try changing that and see if it works.
Thanks for the info. How can we make it so it doesn’t cut off a word then? if I set it to 100 for example, the last word is only part of a word in many cases. It should really go by number of words, not characters if possible.
