Wordpress Hatom problem

[reisefm]

Hi, in Webmaster Tools i receive the following warnings:

hatom-feedhatom-entry:Warning: At least one field must be set for HatomEntry.Warning: Missing required field "entry-title".Warning: Missing required field "updated".Warning: Missing required hCard "author".I googled a few strategies how to solve this problem but is it for SEO purpose really necessary to edit Theme core code to satisfy google's warnings?

I would fix those. Here is a good guide

Fixing it will make sure Google is getting all of the data about your site that it needs which can help you

What usually happens with these sorts of warnings is that WordPress likes to strip out micro-format data. Without seeing the site or knowing what you're trying to accomplish, I can't very well help you diagnose the problem. Ultimately you'll want to look through the microformats syntax and see what your code is lacking.

You may need to modify the theme (e.g. the div around the author) or use a plugin to help with author hCards. If author info is all you care about, it's generally enough to add the proper tags and links to the author bio on the post. I've never used any plugins  for microformats.org, but there are plenty: http://wordpress.org/plugins/tags/hcard

Are you tied to microformats.org? I've successfully used http://wordpress.org/plugins/all-in-one-schemaorg-rich-snippets/ for schema.org snippets.
