Excerpt textarea missing on post editing page in admin panel
Pregunta
Why is that? It's a new installation.
EDIT: I don't have plugins installed and I tried to restore default theme to Twenty Ten, but it didn't change anything.
Solución
Upper right corner in posts editing page > "Screen Options"...there you have to check "Excerpt" ;)
Otros consejos
If you already tried to add it at Screen Options in Upper Right Corner (in older versions)... try it:
Add the following code to your theme’s functions.php file or a site-specific plugin:
add_post_type_support( 'page', 'excerpt' );
