Copy the file plugins>system>jat3>base-themes>default>blocks>navhelper.php to templates>ja_cloris>blocks>navhelper.php
Open the file in its new location and you will see the following
<div class="ja-breadcrums">
<strong><?php echo JText::_('You are here')?></strong> <jdoc:include type="module" name="breadcrumbs" />
</div>
If you remove that the “You Are Here” will go.
Then we need to edit the “Top”. As you can see from the code
<?php echo JText::_('Top') ?>
The JText:: means there should be a language string somewhere for it.
I already know that it is administrator>language>en-GB>en-GB.ini at line 556
00555: TOOLS=Tools
00556: TOP=Top
00557: TRASH=Trash
Had I not known I could have used the excellent and free wingrep (http://www.wingrep.com/) to search through the language folder in just a few seconds for the language string I was looking for. With this excellent tool al you need to do is right click on a folder, click on wingrep then type in the string you are looking for. It then does all the work of finding it for you.
