mypaymkt Hi
If you're using a custom HTML module to show this alert, you can try this way:
1/ Open the override layout file of custom HTML module:
/templates/ja_purity_iv(your default template)/html/mod_custom/default.php (if you don't have this override layout yet, you can copy from base folder in T4 plugin: /plugins/system/t4/themes/base/html/mod_custom/default.php)
2/ Add this line of code:
JHtml::_('bootstrap.framework');
It will look like this:
<?php
/**
* @package Joomla.Site
* @subpackage mod_custom
*
* @copyright Copyright (C) 2005 - 2020 Open Source Matters, Inc. All rights reserved.
* @license GNU General Public License version 2 or later; see LICENSE.txt
*/
defined('_JEXEC') or die;
JHtml::_('bootstrap.framework');
?>
<div class="custom" <?php if ($params->get('backgroundimage')) : ?> style="background-image:url(<?php echo $params->get('backgroundimage'); ?>)"<?php endif; ?> >
<?php echo $module->content; ?>
</div>
Then clear all caches.
