It seems to be working fine for me here.
It is a browser issue. It doesn't work on Google Chrome but works fine on Firefox.
After debugging, i found this line to be the issue
function confirmDelete(form = 'list-form') {
You can replace the entire confirmDelete() {} function in the admin/views/themes/tastyigniter-blue/footer.php file around line 29 with
function confirmDelete(form) {
if ($('input[name="delete[]"]:checked').length && confirm('<?php echo lang('alert_warning_confirm'); ?>')) {
form = (typeof form === 'undefined' || form === null) ? 'list-form' : form;
$('#'+form).submit();
} else {
return false;
}
}
