Themes - Disable ads in Login and Register

[eurobank]

This code doesn't seem to work with Osclass 5 (and probably older versions).

Any ideas what is wrong with the code? I try to change it in theme main.php

<?php if ( ( osc_get_preference('header-728x90', 'osclasswizards_theme') !="") && ( !osc_is_login_page() && !osc_is_register_page() )) { ?>

<div class="ads_header ads-headers"> <?php echo osc_get_preference('header-728x90', 'osclasswizards_theme'); ?> </div>

<?php } ?>

Ok, the code should be placed in header.php and not main.php
