I’m trying to build a theme, I want to control the length of the post excerpts by doing something like this in functions.php:
function theme_excerpt_length( $length ) {
return 45;
}
add_filter( 'excerpt_length', 'theme_excerpt_length', 999 );
But it doesn’t seem to have the desired effect of reducing length of excerpt to 45 words. Even, without the function, some excerpts are longer than the default 55 words. What could be wrong?
