Yes, I did some change to the T3 framework, to remove the worse offenders from Google Structured data. I also use ReReplacer to remove some of the bad data also generated by Joomla and the T3 framework.
Still, I feel this is completely messed up. I'm sure no self-respecting WordPress theme provider would allow such errors to be present in their themes. I keep getting disappointed by the Joomla community, over and over again.
At the very least, please point me to the place where the organization for the author is being generated, I want to drop that asap.
I'll have to keep an eye on my organic traffic following the update, if it dips, it's a problem of the theme.
