Acontece-me no Chrome:
"This page contains the following errors:
error on line 21 at column 20: Namespace prefix g on plusone is not defined
Below is a rendering of the page up to the first error."
E quando meto o link no feedburner aparece
"The URL does not appear to reference a valid XML file. We encountered the following problem: Error on line 21: The prefix "g" for element "g:plusone" is not bound."
