Search works! It actually uses the default function that comes with every WP theme.

I am sure this problem isn’t caused by my theme.

Documentation

It is possible if you know your way around customizing the theme.

To make the thumbnails square go in functions.php find:

add_image_size( 'ac-slide-thumbnail', 515, 300, true );

replace it with:

add_image_size( 'ac-slide-thumbnail', 515, 515, true );

You should also regenerate all your thumbnails or deactivate/activate the theme.

Maybe look for it in ../page-templates/template-page.php

That’s how the theme was designed.

The link is in the documentation, read me file, theme release page.

Open author.php and delete these lines:

<?php if ( have_posts() ) : ?>
    	<header class="main-page-title">

        	<h1 class="page-title"><?php the_post(); printf( __( 'All posts by <span>%s</span>', 'acosmin' ), get_the_author() ) . ac_icon( 'angle-down' ) ?></h1>

            <aside class="about-share clearfix">
                <div class="as-wrap clearfix">

                        $display_name		= get_the_author_meta( 'display_name', $author_id );
                        $user_url			= get_the_author_meta( 'user_url', $author_id );

I tried a child theme (with the latest parent theme version, v1.0.4) on a smartphone and tablet in works as it was intended, out of the box.

I don’t know what changes you’ve made or what plugins you have activated.
