Hi zonemom,
In the current version, there is not a setting that hides the author.
But there is a solution if you use the Custom Formatting feature…
You can adjust the Custom Formatting for the author element to hide it via a css display directive. This is found on the ‘Custom Formatting’ tab in the SP Admin Panel.
Set the author element to be wrapped as follows:
<span style="display: none;">author</span>
After you update the settings, be sure to clear the output cache to ensure that the output is re-rendered.
I just tested this out on the SP test page and it hides the author.
Best regards,
SP Developer
