Hi,
Currently maximum number widgets areas is 5. If you need more, you might need to adjust the respective code for it in the main theme’s file: inc/classes/class-botiga-footer.php. The lines you might need to edit:
<div class="footer-widgets visibility-<?php echo esc_attr( $visibility ); ?>">
<?php do_action( 'botiga_footer_widgets_content_start' ); ?>
<div class="<?php echo esc_attr( $container ); ?>">
<div class="footer-widgets-grid <?php echo esc_attr( $layout ); ?> align-<?php echo esc_attr( $alignment ); ?>">
<?php for ( $i = 1; $i <= $column_no; $i++ ) { ?>
<?php if ( is_active_sidebar( 'footer-' . $i ) ) : ?>
<div class="widget-column">
<?php dynamic_sidebar( 'footer-' . $i); ?>
</div>
<?php endif; ?>
<?php } ?>
</div>
</div>
<?php do_action( 'botiga_footer_widgets_content_end' ); ?>
</div>
