Hi there
Your question is not completely clear to me, you do not want modules published in your new page or you do not want mainmenu in this page ?
in the first case you can disable module publishing in the specific page editing the module and in menu assignment you can not publish it in your new page.
in the second case you can copy header.php file and rename it for example headernomain.php and remove from it this part of code <?php $this->loadBlock (‘mainnav’) ?>
so you should change :
<!-- //LOGO -->
<?php $this->loadBlock ('mainnav') ?>
<?php if ($this->countModules('head-search')) : ?>
TO :
<!-- //LOGO -->
<?php if ($this->countModules('head-search')) : ?>
Then copy your layout file for example default layout in this folder /templates/uber/tpls/default.php and rename it defaultnomain.php and change from :
<?php $this->loadBlock('header') ?>
<?php $this->loadBlock('masthead') ?>
<?php $this->loadBlock('submenu') ?>
TO:
<?php $this->loadBlock('headernomain') ?>
<?php $this->loadBlock('masthead') ?>
<?php $this->loadBlock('submenu') ?>
Then create a new mwnu item and assign to it the defaultnomain layout
remember to disable the acm header module from the new page in menu assignment
Hope it helps
