Sorry for not replying early. I just saw your question today.
I was checking your question and I found a bug on my code, thank you for that.
First you will need to overwrite the function which is not working as it should on function.php at line 412. Replace lines 412 until 468 with the following code:
function lupercalia_post_thumbnail( $args ) {
if ( has_post_thumbnail() ) : ?>
<?php if ( $args[‘link’] == true ) : ?>
<div class=”entry-thumbnail”>
“><?php the_post_thumbnail( $args[‘size’] ); ?>
<?php if( $args[‘date’] == true) : ?> <p class=”icon-clock”><?php echo get_the_date(); ?></p> <?php endif; ?>
</div> <!– .entry-thumbnail –>
<?php else: ?>
<div class=”entry-thumbnail”>
<?php the_post_thumbnail( $args[‘size’] ); ?>
<?php if( $args[‘date’] == true) : ?> <p class=”icon-clock”><?php echo get_the_date(); ?></p> <?php endif; ?>
</div> <!– .entry-thumbnail –>
<?php endif; ?>
<?php else : ?>
<?php if ( $args[‘sample’] == true ) : ?>
<?php if ( $args[‘link’] == true ) : ?>
<div class=”entry-thumbnail”>
“><img src=”<?php echo get_template_directory_uri(); ?>/imgs/post/no-thumbnail.jpg” />
<?php if( $args[‘date’] == true) : ?> <p class=”icon-clock”><?php echo get_the_date(); ?></p> <?php endif; ?>
</div> <!– .entry-thumbnail –>
<?php else: ?>
<div class=”entry-thumbnail”>
<img src=”<?php echo get_template_directory_uri(); ?>/imgs/post/no-thumbnail.jpg” />
<?php if( $args[‘date’] == true) : ?> <p class=”icon-clock”><?php echo get_the_date(); ?></p> <?php endif; ?>
</div> <!– .entry-thumbnail –>
<?php endif; ?>
<?php endif; ?>
<?php endif;
}
After that, you will need to change the files content-single.php (line 9) and content.php (line 11) replace where ‘date’ => true to ‘date’ => false.
About your question 2, this theme not allows to change the number of columns.
