Calendar in Widget

Nvm figured it out myself

Go to theme’s function.php and just add – add_filter('widget_text', 'do_shortcode'); on top or the bottom I’ve put it here –

<?php

# option-tree start
add_filter('ot_show_pages', '__return_false');
add_filter('ot_theme_mode', '__return_true');
add_filter('widget_text', 'do_shortcode');
