There may be a more dynamic way of targeting this with a little PHP but I am unaware of it if there is.
If you’re using the child theme the following method should work for you – this assumes that you’re running the very latest theme update.
1. Create a folder in your child theme called page-parts
2. Copy general-header-section.php
located in the main theme (this can be found at /wp-content/themes/kleo/page-parts/general-header-section.php
) to your newly created folder
3. Edit line 152 of the file general-header-section.php
in your child theme and replace <a href="<?php echo home_url(); ?>">
with <a href="http://www.MYDOMAINNAMEHERE.com">
Remember to always backup the original file locally before making any changes.
