Display only excerpts of posts in home page

(1) install the plugin “show current template” to find out what template is being used to show the content

(2) create a child theme — https://codex.www.ads-software.com/Child_Themes

(3) copy the file you identified from (1) into the child theme and modify it so instead of using the_content(), it uses the_excerpt() https://developer.www.ads-software.com/reference/functions/the_excerpt/

I did the two first steeps but i’m stuck with steep 3 (I’m not a man of the field), and I don’t see any ‘the_content()’ or ‘the_excerpt()’ in the file I’m trying to edit (index.php)..so I don’t know what to edit.
here is a link to the code:

what should I do !!
thank you.

the code is in one of those template parts, post-homepage.php or post.php

the code is not in ‘post.php’ file, and ‘post-homepage.php’ file does not exist (it is only to be created apparently).
for info:everything was working well before I added categories to menu. but since I put categories in place of menu items, my Home menu link disappeared (I only created a link referring it to home page) and post started displaying full on home page.

What theme are you using?

I’m using Paso (downloaded from flexithemes)

I’m sorry but as you appear to be using a non-WPORG theme, you need to seek support from the theme’s developers – paid or otherwise. We only support themes downloaded from www.ads-software.com here.
