From Joomla! Documentation
The original JA Purity template was provided from JoomlArt.com as a zip but the latest files have been installed along with Joomla. The relevant files, index.php, can be found in templates/ja_purity. If you've been following the tutorial, you can download a tutorial version of the template that installs to the templates/my_japurity folder. Inside the folder of the template, the files are located as follows:
<location of template>/
index.php
Comment out this line: <?php $tmpTools->genToolMenu(JA_TOOL_FONT, 'png'); ?>
