Own pagination

Hi Artur, the plugin’s installation guide provides some guidance on how to modify pagination:

Don’t edit the theme files directly, though, as your tweaks will be overwritten and lost every time you update the theme. Instead, create a child theme and add your plugin code to that. Here are some guides in case you haven’t made one before:

In Sela, the posts navigation is on index.php on line 21:

<?php sela_content_nav( 'nav-below' ); ?>

I’d suggest copying index.php into your child theme, replacing line 21 with your plugin’s function, and seeing how it goes.

Glad to hear it! Feel free to start a new thread if you need help with anything else.
