adjusting truncate function on post excerpts

Hi,

I’m trying to change the value for a truncate function. I would like the entire post to be visible (it is a short post) but the truncate function seems to truncate at 230 spaces. I’ve tried changing this value 300-400, but no difference. When I lower it though (e.g. to 20) it does work. Anyone know how to fix this? Here is the code I believe I need to change, but could be wrong:

code
$arr[$i][“excerpt”] = truncate_post(500,false);
/code

I am using ElegantEstate, file featured.php

Any help would be much appreciated.
