What file contains homepage?

Hello,

In the old site I used excerpts and now I find that the length is too big. I have already put this code in M16:

<div class=”td-excerpt”>
<?php echo wp_trim_words(get_the_excerpt(), 30); ?>
</div>

I would like to also put the same code in the homepage so I don’t have to manually shorten the excerpt of all my old articles (see this example, http://screencast.com/t/ZLVhak2rydH). Where should I put my code?

Thank you!

I don’t think I explained myself properly.

I cannot control excerpts from Theme Panel because unfortunately for the last few years I have been writing excerpts via the WordPress facility. Now I have discovered that they are too long for this theme, as you can see in this screenshot: http://screencast.com/t/cMu09dXshzH.

I need a way to automatically shorten my excerpts on the homepage. I have recreated your default demo so I am using quite a lot of blocks. My problem is where to add the code.

I had the same problem in the categories page but I added this code to M16 and it resolved the issue:

<div class=”td-excerpt”>
<?php echo wp_trim_words(get_the_excerpt(), 30); ?>
</div>

Thanks in advance!

It doesn’t work, I’m afraid. I went from a huge excerpt appearing in the homepage to none at all!

This is the code I entered: http://screencast.com/t/sBcSHfD43 and this is what I got in the homepage: http://screencast.com/t/VhVm2GU8VSGa

What next?

Thanks!
