The issue relates to the fact that search bots are following the email button, which is trigging the Admin Tools security exceptions. So, it’s not an issue (you’ll not see any warnings) if there is no firewall component installed. Still, the fact that Google and others are following and indexing in particular the “Send to Friend” page, which useless for SEO, is not good thing.
So, what I did. In files:
/templates/ja_teline_iv/html/com_content/article/default.php
/templates/ja_teline_iv/html/com_content/category/blog_item.php
found[PHP]<?php echo JHtml::_(‘icon.email’, $this->item, $params); ?>[/PHP]
and replaced with [PHP]<?php echo JHtml::_(‘icon.email’, $this->item, $params, array(‘rel’ => ‘nofollow’)); ?>[/PHP]
This added “nofollow” attribute to the email link (such an attribute is added by default to the print icon by Joomla, why it’s not to the email button – that’s a good question…).
Moreover, in robots.txt I added
# Do not index email to friend button
Disallow: /component/mailto/*
Disallow: /index.php?option=com_mailto*
