I had an additional information tab on our product view page which displayed Attributes set to be 'Visible on Product View Page on Front-end'.
I deleted the attributes as they had been named incorrectly but when I created a new attribute with the same setting & in the correct attribute group it does not show in a additional information tab anymore. The additional information tab seems to be not working.
I've checked the store scope when I added content to the new attribute from the Manage Products > Edit Product admin page. I'm not sure what I could be missing?
I've refreshed my cache & re-indexed too.
Here are my screen shots of the setting.

I found the problem. There is an extension on the our Magento Instalation called amasty color swatches which has a script on the page which disables the additional info tab.
here it is:
I was unable to disable this setting from the extensions settings on the admin panel. I had to comment out line 62 of
app/code/local/Amasty/Conf/Block/Catalog/Product/View/Type/Configurable.php
I don't think this is a good solution though as the extension is grabing this data to swap simple product attributes with the parent configurable product attributes on the product view page. I think the whole issue arises as the module is not compatible with Magento 1.9 rwd theme which puts the additional information in a tab.
