Archives full?

Hi everyone,

I am a member of the admin team for a community technology blog called Technology Bloggers.

I have recently noticed that after page 26, our archives just stop – https://www.technologybloggers.org/page/26/ at the moment, 3 post are missing.

Currently three posts only show on the homepage and 10 posts are set to be displayed on every other page.

The code used is

<?php
			/* Run the loop to output the posts.
			 * If you want to overload this in a child theme then include a file
			 * called loop-index.php and that will be used instead.
			 */
			 get_template_part( 'loop', 'index', 'home');
			?>

in the newly created ‘home.php’ file and https://pastebin.com/8qy6nZY6 in the loop-home.php file.

If I set the number of post to show to 5, then the missing posts reappear, but we get lots more archive pages – in the 50’s.

I think it is something to do with the homepage only show 3 posts code, but am not sure what… any ideas anyone?

All help and advice really appreciated!

Thanks ??
Christopher
