I am using v1.5.1

Years ago I had some text, not a link in the top navigation bar where the search box should have been. I added the text and it worked to my includes/template/custom/common/header.php

The old code that worked is below
<div id="navMainSearch"> My text here.</div> My text was aligned to the right.

In 1.5.1 the code is different and my text won't display. The code in the new file is...

<div id="navMainSearch"><?php require(DIR_WS_MODULES . 'sideboxes/search_header.php'); ?></div>

I have tried inserting my text here <div id="navMainSearch">MY TEXT it didn't work.

Then I tried it here 'sideboxes/search_header.php'); ?>MY TEXT</div> again it didn't work.

Can anybody help me please?

Thanks.
