There is a know issue for the metatag not displaying on the front page. If you read the README.txt in the module file. Between line 281 and 292 you can find following description.
Troubleshooting / known issues
--------------------------------------------------------------------------------
* When using custom page template files, e.g., page--front.tpl.php, it is
important to ensure that the following code is present in the template file:
<?php render($page['content']); ?>
or
<?php render($page['content']['metatags']); ?>
Without one of these being present the meta tags will not be displayed.
* An alternative method to fixing the missing-tags problem is to change the page
region used to output the meta tags. The region used may be controlled from
the settings page, it is recommended to test different options to identify the
one that works best for a specific site.
If this is the case, you can look at this issue it you are using customized template.
That issue has already been registered at the Metatag module's Issue section,
SOLUTION: Metatags in front not working
Additional: If you wan to Add using Views
You can get additional setting for the Frontpage
. Go to admin/structures/views
-> There you can find one view name frontpage
, which is not enabled by default. You can enable that view. That view is a front-page for your Drupal site.
It has been provided by views
as default to open up new setting for front page. Now you can add, modify whatever field you want. I hope this way you are able to access that.
