Hi @davidsortof,
Thanks for the reply! I actually did figure out how to make this work later. I created an index.php file in my Astra child theme folder (creating a child theme helps prevent the problem of having the code erased when the theme updates). Then I copied all of the code from my Astra index.php file into the new index.php file in my child theme. Then below where it said “get_header(); ?>” I inserted this line of code:
<div align=”center”><span style=”font-size: 60px;”> </br> <?php single_post_title(); ?></div>
You can then change the alignment and font size to suit your needs. This finally fixed my problem! I hope this might be helpful to anyone else trying to make this work!
