Structured Data > hatom (markup: microformats.org) Error: Missing: author

Hi Tomas,

When checking my Webmaster Tools for my blog, I have come across errors in the Structured Data area. Specifically, the error is ‘Missing: author’.

An example link to where this is occurring is here:

I have searched about WordPress forums, and most seem to indicate that it could be an issue with the theme, though I’m unsure of that, and wanted to check here to see if anyone else has come across this.

Thanks always,
Coleen
