Hello,
1/ Add the next code in functions.php of your child theme:
add_filter('etheme_sticky_cart_title', function ($title, $full_title) {
return $full_title;
}, 10, 2);
Filter to show full title in sticky panel instead of cropped one by 30 chars.
2/ Download navigation-prev-next.php file from this page – https://dropmefiles.com.ua/en/T6H7fGEs and upload it into /wp-content/themes/xstore/templates folder, then add the next code in functions.php of your child theme
add_filter('etheme_prev_next_title', function ($title, $full_title) {
return $full_title;
}, 10, 2);
Regards
